Proton transfer processes mediate many organic reactions. How to realize stereochemical control of this process has always been a challenging topic in the field of asymmetric catalysis. In this study, N-(diphenylmethyl)-1-phenylethan-1-imine (Schiff base derived from 2,2-diphenylethan-1-amine and acetophenone) was used as substrate, and different near neutral solvents and various chiral metal complex catalysts were used to carry out photoinduced C=N double bond transfer in the substrate under irradiation with a mercury ultraviolet lamp. The double bond transfer in the substrate molecule was highly selective. Solvents containing strong electronegative atoms like oxygen and chlorine, such as alcohols, aldehydes, and carbon tetrachloride, were more effective than other solvents under high light intensity. The 1,3-proton transfer process involves photoexcitation of the Schiff base and coordination of the latter to the central metal atom of the chiral catalyst, so that the substrate molecule is placed in a stable chiral environment to form a transition state. The strongly electronegative atom of the near-neutral solvent attracts the active a-hydrogen from the excited Schiff base molecule to form a negatively charged delocalized p-bond structure. The subsequent proton addition yields more stable molecular structure to complete the selective proton transfer process. Among the examined chiral catalysts, divalent tin porphyrin was the most effective, and the product yield and enantiomeric excess were 98% and 91.49%, respectively. The described photoinduced C=N double bond transfer in N-(diphenylmethyl)-1-phenylethan-1-imine is characterized by mild conditions (room temperature), high stereoselectivity, and simple operation.

N,N’-Acetals are sensitive compounds, and the challenging asymmetric synthesis of acyclic N,N’-acetals by the general addition of amines to ketimines has never been reported so far. In this study, highly enantioselective addition of aryl amines to isatin-derived ketimines catalyzed by chiral urea derived from quinine was developed. A series of new acyclic N,N’-acetals were constructed by this protocol in high to excellent yields (78-99%) and high to excellent enantioselectivities (76-96% ee).

The capsid protein (CA) of HIV-1 plays essential roles in multiple steps of the viral replication cycle by assembling into functional capsid core, controlling the kinetics of uncoating and nuclear entry, and interacting with various host factors. Targeting CA represents an attractive yet underexplored antiviral approach. Of all known CA-targeting small molecule chemotypes, the peptidomimetic PF74 is particularly interesting because it binds to the same pocket used by a few important host factors, resulting in highly desirable antiviral phenotypes. However, further development of PF74 entails understanding its pharmacophore and mitigating its poor metabolic stability. We report herein the design, synthesis, and evaluation of a large number of PF74 analogs aiming to provide a comprehensive chemical profiling of PF74 and advance the understanding on its detailed binding mechanism and pharmacophore. The analogs, containing structural variations mainly in the aniline domain and/or the indole domain, were assayed for their effect on stability of CA hexamers, antiviral activity, and cytotoxicity. Selected analogs were also tested for metabolic stability in liver microsomes, alone or in the presence of a CYP3A inhibitor. Collectively, our studies identified important pharmacophore elements and revealed additional binding features of PF74, which could aid in future design of improved ligands to better probe the molecular basis of CA-host factor interactions, design strategies to disrupt them, and ultimately identify viable CA-targeting antiviral leads.

A simple protocol for the protection of amines was realized through a base-catalyzed one-pot reaction of dimedone, beta-nitroalkene, and amine. Employing this strategy, a variety of amines/amino acids were protected in excellent yields. These acid/base stable protected amines can be deprotected by either ethylene diamine or hydrazine hydrate under mild conditions. The practical application of this orthogonal protecting group was demonstrated by the synthesis of cyclic peptide melanotan II via SPPS.

Electroorganic synthesis is an environmentally friendly alternative to traditional synthetic methods; however, the application of this strategy is heavily hindered by low product selectivity. Metal-organic frameworks (MOFs) exhibit high selectivity in numerous catalytic reactions; however, poor conductivity heavily limits the application of MOFs in electroorganic synthesis. To realize the electrocatalytic application of MOFs in selective electroorganic synthesis, a practically applicable strategy by suspending ion electrocatalysts in charged MOFs is herein reported. This approach could markedly improve the product selectivity in electroorganic synthesis. In the electrocatalytic oxidative self-coupling of benzylamine experiments, the imine product selectivity is markedly improved from 61.3 to 94.9 %, when the MOF-based electrocatalyst is used instead of the corresponding homogeneous electrocatalyst under the identical conditions. Therefore, this work opens a new route to improve the product selectivity in electroorganic synthesis.

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.

A simple and efficient protocol for the formylation of amines with formic acid, catalyzed by a polyoxometalate-based chromium catalyst, is described. Notably, this method shows excellent activity and chemo-selectivity for the formylation of primary amines; diamines have also been successfully employed. Importantly, the chromium catalyst is potentially non-toxic, environmentally benign and safer than the widely used high valence chromium catalysts such as CrO3 and K2Cr2O7. The catalyst can be recycled several times with a negligible impact on activity. Finally, a plausible mechanism is provided based on the observation of intermediate and control experiments.
