Liu, Wen-Xing; Chen, Si-Kai; Tian, Jin-Miao; Tu, Yong-Qiang; Wang, Shao-Hua; Zhang, Fu-Min published the artcile< A Triazole Organocatalyst with Spiropyrrolidine Framework and its Application to the Catalytic Asymmetric Addition of Nitromethane to α,β-Unsaturated Aldehydes>, COA of Formula: C9H7BrO, the main research area is triazole spiropyrrolidine organocatalyst preparation; stereoselective nitromethane Michael addition unsaturated aldehyde.
A series of new water-compatible “”spiropyrrolidine triazole”” catalysts was designed and synthesized. The asym. Michael addition of nitromethane and α,β-unsaturated aldehydes in an aqueous system was investigated to evaluate these new catalysts, and the resulting adducts were obtained with excellent enantioselectivity (up to 95.5% ee) and moderate to good yield (63-88%).
Advanced Synthesis & Catalysis published new progress about Enantioselective synthesis. 3893-18-3 belongs to class bromides-buliding-blocks, and the molecular formula is C9H7BrO, COA of Formula: C9H7BrO.
