Recently I am researching about CHIRAL SYNTHESIS; ORGANIC AZIDES; ORGANOBORANES; PYRROLIDINE; PIPERIDINE; AMINES; PYRIDINE, Saw an article supported by the PfizerPfizer. Published in AMER CHEMICAL SOC in WASHINGTON ,Authors: Xu, PL; Zhang, MK; Ingoglia, B; Allais, C; Dechert-Schmitt, AMR; Singer, RA; Morken, JP. The CAS is 93-97-0. Through research, I have a further understanding and discovery of Benzoic anhydride. COA of Formula: C14H10O3
Intramolecular amination of organoboronates occurs with a 1,2-metalate shift of an aminoboron ate complex to form azetidines, pyrrolidines, and piperidines. Bis(boronates) undergo site-selective amination to form boronate-containing azacycles. Enantiomerically enriched azacycles are formed with high stereospecificity.
COA of Formula: C14H10O3. About Benzoic anhydride, If you have any questions, you can contact Xu, PL; Zhang, MK; Ingoglia, B; Allais, C; Dechert-Schmitt, AMR; Singer, RA; Morken, JP or concate me.
