《BIMP-Catalyzed 1,3-Prototropic Shift for the Highly Enantioselective Synthesis of Conjugated Cyclohexenones》 was published in Angewandte Chemie, International Edition in 2020. These research results belong to Golec, Jonathan C.; Carter, Eve M.; Ward, John W.; Whittingham, William G.; Simon, Luis; Paton, Robert S.; Dixon, Darren J.. Recommanded Product: 36016-38-3 The article mentions the following:
A bifunctional iminophosphorane (BIMP)-catalyzed enantioselective synthesis of α,β-unsaturated cyclohexenones through a facially selective 1,3-prototropic shift of β,γ-unsaturated prochiral isomers, under mild reaction conditions and in short reaction times, on a range of structurally diverse substrates, is reported [e.g., I → II (90%, 99% ee)]. α,β-Unsaturated cyclohexenone products primed for downstream derivatization were obtained in high yields (up to 99%) and consistently high enantioselectivity (up to 99% ee). Computational studies into the reaction mechanism and origins of enantioselectivity, including multivariate linear regression of TS energy, were carried out and the obtained data were found to be in good agreement with exptl. findings. After reading the article, we found that the author used N-tert-Butoxycarbonylhydroxylamine(cas: 36016-38-3Recommanded Product: 36016-38-3)
N-tert-Butoxycarbonylhydroxylamine(cas: 36016-38-3) belongs to anime. Reduction of nitro compounds, RNO2, by hydrogen or other reducing agents produces primary amines cleanly (i.e., without a mixture of products), but the method is mostly used for aromatic amines because of the limited availability of aliphatic nitro compounds. Reduction of nitriles and oximes (R2C=NOH) also yields primary amines.Recommanded Product: 36016-38-3
