Without using chiral sources, the Strecker reaction of achiral hydrogen cyanide, p-tolualdehyde and benzhydrylamine gave enantioenriched L- or D-N-benzhydryl-alpha-( p-tolyl) glycine nitriles with up to > 99% ee in a mixed solvent of water and methanol. Therefore, total spontaneous resolution of alpha-aminonitriles could occur through a prebiotic mechanism of alpha-amino acid synthesis. Moreover, it was demonstrated that the repetition of partial dissolution and crystallization of a suspended conglomerate of aminonitrile under solution-phase racemization could generate the enantiomeric imbalance to afford, in combination with the amplification of chirality, an enantioenriched product in every case. Among the 73 experiments that were carried out, D-and L-enriched isomers occurred 36 and 37 times, respectively. This stochastic behavior, under achiral or racemic starting conditions, meets the requirements of the spontaneous absolute asymmetric Strecker synthesis. The implications of the present results for the origin of chirality of alpha-amino acids are discussed.

Using the easily accessible 2-azaallyl anions as initiators, the one-pot synthesis of well-defined primary amine-ended telechelic polyaziridines (alpha-NH2 PAzs) has been achieved through the ring-opening polymerization (ROP) of N-sulfonyl aziridines followed by hydrolysis of the diphenylketimine moiety (-N=C-Ph-2). The 2-azaallyl anions were synthesized from the reaction of diphenylketimine or N-[aryl-methylene]-alpha-phenylbenzenemethanamine with potassium bis(trimethylsilyl) amide (KHMDS) in situ and used to initiate the ROP of aziridines leading to well-defined alpha-(Ph2C=N)-alpha’-aryl-omega-NH PAzs. Along with the diphenylketimine group (-N=C-Ph-2), aryl functionalities, such as pyridine and triphenylphosphine moieties, can also be incorporated to the chain end. Chain extension has been applied for the synthesis of poly(N-sulfonyl aziridine)-block-poly(epsilon-caprolactone) (PAz-b-PCL) block copolymers by utilization of the primary amine end group as initiating sites for the ROP of epsilon-caprolactone catalyzed by tin 2-ethyl hexanoate (SnOct(2)). Taking advantage of this synthetic approach, core cross-linked multiarm star (CCS) polymers with an outermost shell having amino and triphenylphosphine functionalities have been synthesized via arm-first strategy.

Glecaprevir was identified as a potent hepatitis C virus (HCV) protease inhibitor, and a large-scale synthesis was required to support the late-stage clinical trials and subsequent commercial launch. The large-scale synthetic route to glecaprevir required the development of completely new synthetic approaches to the two key structural features: the 18-membered macrocycle 3 and the difluoromethyl-substituted cyclopropyl amino acid 4. In this first manuscript, we describe the route development for the macrocycle 3; the second manuscript will describe the development of a new synthetic route to the difluoromethyl-substituted cyclopropyl amino acid 4 and the final assembly of glecaprevir. The large-scale synthetic route to the macrocycle employed a unique intramolecular etherification reaction as the key step in the macrocycle synthesis, avoiding the scalability limitations of the ring-closing metathesis (RCM) reaction of the enabling route. The large-scale synthetic route to the macrocycle was successfully used to produce the amount of glecaprevir required to support the late-stage clinical development.

Several phenoxy-imine ligands bearing o-trityl group in phenoxy moiety RN=CHArOH (Ar = C6H2(CPh3)Bu-t, R = 2,6-Me2C6H3 (L1H); 2,6-(Pr2C6H3)-Pr-i (L2H); 3,5-(CF3)(2)C6H3 (L3H); 3,5-(OMe)(2)C6H3 (L4H); CHPh2 (L5H); CPh3 (L6H)) were synthesized and characterized by H-1 NMR and C-13 NMR spectroscopy. The vanadium complexes based on these ligands LVCl2(THF)(2) (1-6) were synthesized via conventional transmetalation reaction in moderate to high yields. Complexes 1-6 were fully characterized by FT-IR, elemental analyses and the molecular structures of 1, 2 center dot H2O, (2 center dot H2O)(2)(mu-Cl)(2), 4, and 5 were confirmed by X-ray crystallographic analysis in which the six-coordinated vanadium centers are in a typical octahedral geometry. Upon activation with Et2AlCl in toluene, complexes 1-6 showed high activities in ethylene polymerization affording polymers with moderate molecular weight (5.9-11.8 x 10(4) Da). Moreover, in hexane or CH2Cl2, 1-6/Et2AlCl exhibited enhanced activities. When activated with MAO or MMAO in toluene, these complexes showed relatively low activities but afforded polymers with ultra-high molecular weight (up to 3.30 x 10(6) Da). 1-6/Et2AlCl also showed high activities in ethylene/1-hexene copolymerization at room temperature giving moderate molecular-weight polymers (6.5-11.4 x 10(4) Da) with co-monomer incorporation being of 6.0 similar to 7.8%.

Under different pathological conditions, aberrant induction of neuronal nitric oxide synthase (nNOS) generates overproduction of NO that can cause irreversible cell damage. The aim of this study was to develop an amidoxime prodrug of a potent nNOS inhibitor, the benzhydryl acetamidine. We synthesized the benzhydryl acetamidoxime, which was evaluatedin vitroto ascertain the potential NOS inhibitory activity, as well as conducting bioconversion into the parent acetamidine. The prodrug was also profiled forin vitrophysicochemical properties, by determining the lipophilicity, passive permeation through the human gastrointestinal tract and across the blood-brain barrier by PAMPA, and chemical, enzymatic, and plasma stability. The obtained data demonstrate that the amidoxime prodrug shows an improved pharmacokinetic profile with respect to the acetamidine nNOS inhibitor, thus suggesting that it could be a promising lead compound to treat all those pathological conditions in which nNOS activity is dysregulated.

Cyclic aminomethylphosphines in general and 1,5-diaza-3,7-dihposphacyclooctanes in particular are widely used for the design of d(10)-metal complexes with catalytic or luminescent properties. 1,5-Diaza-3,7-diphosphacyclooctanes are chelating ligands towards Ni subgroup metals and chelating or bridging ligands towards copper subgroup metals. These ligands can be utilized for the design of polynuclear complexes with stimuli-responsive luminescence. Nowadays several complexes based on 1,5-diaza-3,7-diphosphacyclooctanes demonstrating stimuli-response of emission towards organic substrates or temperature are known. Some of the gold(I) complexes are able to sensitize the luminescent anionic rhenium cluster. Copper(I) complexes display rather strong luminescence with quantum yields 20-40%. [GRAPHICS] .

Three AIE (aggregation-induced emission)-ESIPT (excited-state intramolecular proton transfer) active 2-(2-hydroxyphenyl)benzothiazole derivatives, HL1, HL2 and HL3 with one, two and three rotatable phenyl groups, were obtained and characterized. Their AIE properties in THF/HEPES solution were investigated in detail. HL2 shows the best AIE performance with 71-fold fluorescence enhancement, while HL3 only shows a 9-fold enhancement. With the AIE property, HL1 and HL2 could act as fluorescence chemosensors to detect Cu2+ ions via the turn off mode in THF/HEPES media. With the ESIPT property, HL1 and HL2 could also detect Zn2+ ions via the turn on mode in EtOH/HEPES media. During the detection process, both demonstrate rapid response and high contrast before and after the addition of metal ions. The species formed in the detection system were investigated. The results of X-ray single-crystal diffraction confirm that Zn2+ is coordinated with the oxygen atom and Schiff base nitrogen atom instead of the benzothiazole nitrogen atom in the tetrahedron geometry. Moreover, the chemosensors were successfully constructed into handy fluorescence test papers for Cu2+ and Zn2+ detection.
