On December 31, 2022, Hyder, M.; O’Donnell, A. D.; Chippindale, A. M.; German, I. M.; Harries, J. L.; Shebanova, O.; Hamley, I. W.; Hayes, W. published an article.Name: 1,3-Diphenylurea The title of the article was Tailoring viscoelastic properties of dynamic supramolecular poly(butadiene)-based elastomers. And the article contained the following:

The discovery and development of new adhesive materials is critical for real-world applications of polymeric composite materials. Herein, we report the design and synthesis of a library of structurally related phase-separated supramol. polyurethanes whose mech. properties and adhesive characteristics can be enhanced through minor structural modifications of the polymer end-group. The interplay between phase separation of the hard domain polar end-groups and soft polybutadiene domains, coupled with tuneable self-assembly afforded by the polar end-groups, gives rise to a class of materials with tuneable mech. properties. Exceptionally strong supramol. adhesives and mech. robust self-healing elastomers were identified. The mech. properties were investigated through tensile testing. Finally, rheol. anal. of the supramol. materials was used to identify suitable healing and adhesive temperatures in addition to elucidate the supramol. polyurethanes’ thermal-responsive nature. The experimental process involved the reaction of 1,3-Diphenylurea(cas: 102-07-8).Name: 1,3-Diphenylurea

On August 16, 2019, Yan, Dingyuan; Jiang, Heming; Sun, Wenxue; Wei, Wei; Zhao, Jing; Zhang, Xinhao; Wu, Yun-Dong published an article.HPLC of Formula: 685-91-6 The title of the article was Synthesis of Benzofurans and Benzoxazoles through a [3,3]-Sigmatropic Rearrangement: O-NHAc as a Multitasking Functional Group. And the article contained the following:

The synthesis of heterocycles relies heavily on diverse sigmatropic rearrangements triggered by the cleavage of X-Y (X, Y = C, O, N, S, I) bonds. However, a unified rearrangement approach for constructing heterocyclic libraries is highly desirable. Encouraged by computational anal. of [3,3]-sigmatropic rearrangements, we can now rapidly synthesize oxa-heterocycles by treating N-phenoxyacetamides (Ph-ONHAc) with compounds containing an sp-hybridized carbon. The generality of the process is illustrated by the late-stage diversification of natural products, including estrone and an approved drug. A combination of exptl. and computational studies revealed that the reactions proceed through a facile Claisen-like [3,3]-sigmatropic rearrangement/annulation process. The experimental process involved the reaction of N,N-Diethylacetamide(cas: 685-91-6).HPLC of Formula: 685-91-6

Yingcharoen, Prapussorn; Natongchai, Wuttichai; Poater, Albert; D’ Elia, Valerio published an article in 2020, the title of the article was Intertwined chemistry of hydroxyl hydrogen-bond donors, epoxides and isocyanates in the organocatalytic synthesis of oxazolidinones versus isocyanurates: rational catalytic investigation and mechanistic understanding.Synthetic Route of 102-07-8 And the article contains the following content:

The use of hydroxyl hydrogen bond donors (HBDs) was investigated in cycloaddition of isocyanates to epoxides to afford 3-aryl-2-oxazolidinones I [R1 = H, 2-Me, 4-NO2, etc.; R2 = Et, CH2OCH2CH=CH2, CH2OCH2Ph, etc.] as a class of heterocycles with promising applications in pharmaceutical chem. In this work, a systematic investigation of readily available HBDs as catalytic components of binary systems for latter cycloaddition reaction was carried out. Such a study showed crucial role of HBDs’ pKa1 value in driving selectivity of reaction toward oxazolidinones as opposed to formation of oligomeric isocyanurates or ureas, with most acidic HBDs (pKa1: 3-4) displaying best catalytic performance. Mechanistic investigation with the support of DFT calculations allowed deeper insight into reaction dynamics and origin of exptl. observed chemoselectivity for cyclization vs. cyclo-oligomerization at different reaction temperatures, shedding light on a strictly intertwined chem. between the HBDs, isocyanates and epoxides. The experimental process involved the reaction of 1,3-Diphenylurea(cas: 102-07-8).Synthetic Route of 102-07-8

On January 31, 2018, Fadavi, Abdulhamid; Zarei, Maaroof published an article.Related Products of 27115-50-0 The title of the article was One-pot Vilsmeier reagent-mediated multicomponent reaction: A direct synthesis of oxazolones and Erlenmeyer azlactones from carboxylic acids. And the article contained the following:

N-Acylation of glycine with carboxylic acids RC(O)OH [R = C6H5, 4-pyridyl, 2-naphthyl, CH3CH=CH, etc.] was carried out by using the Vilsmeier reagent. The resulting N-acyl-α-amino acids RC(O)NHCH2C(O)OH were subsequently cyclodehydrated into oxazol-5-ones I via the Vilsmeier reagent. Finally, treatment of oxazol-5-ones I with aldehydes R1CHO [R1 = CH3, C6H5, 2-furyl, etc.] in the presence of the Vilsmeier reagent delivered Erlenmeyer azlactones II. By combining these steps, using the Vilsmeier reagent allowed direct one-pot conversion of carboxylic acids RC(O)OH into oxazol-5-ones I and direct one-pot conversion of carboxylic acids RC(O)OH into Erlenmeyer azlactones in the presence of aldehydes R1CHO. These Vilsmeier reagent-mediated multicomponent reactions proceeded smoothly in reasonable chem. yields at room temperature The chem. structure of the title compounds I and II was confirmed by spectral data. The experimental process involved the reaction of 2-(4-Methylbenzamido)acetic acid(cas: 27115-50-0).Related Products of 27115-50-0
