5-Pyrrolidin-2-yltetrazole is a versatile organocatalyst for the asymmetric conjugate addition of nitroalkanes to enones. Using this catalyst, this transformation requires short reaction times, tolerates a broad substrate scope, and possibly proceeds via generation of an iminium species.
5-吡咯烷-2-基四唑是一种通用的有机催化剂,用于将硝基烷烃不对称地加成成烯酮。使用这种催化剂,这种转化需要较短的反应时间,可以耐受广泛的底物范围,并且可能通过生成亚胺鎓类物质进行。
