Abstract

Rhodium(III)-catalyzed oxidative couplings between N-sulfonyl allylamines and activated olefins have been achieved. Only olefination occurred for acrylates, and the butadiene product can be further cyclized under palladium-catalyzed aerobic conditions. The coupling with N,N-dimethylacrylamide followed a cyclization pathway.

摘要

铑(III)催化的 N-磺酰基烯丙基胺与活化烯烃的氧化偶联已经实现。只有丙烯酸酯发生烯丙基化，而在钯催化的有氧条件下，丁二烯产物可以进一步环化。与 N,N-二甲基丙烯酰胺的偶联遵循环化途径。
