An unprecedented and highly efficient nickel-catalyzed cascade vinylogous Mukaiyama 1,6-Michael/Michael addition of 2-silyloxyfuran with N-sulfonyl-1-aza-1,3-dienes is reported, in which 2-silyloxyfuran was successfully employed as nucleophile and electrophile sequentially. This methodology combined with subsequent reduction provides a facile access to biologically important fused piperidine/butyrolactone
据报道,空前的,高效的镍催化的级联乙烯基Mukaiyama 2-silyloxy呋喃与N-磺酰基-1-aza-1,3-二烯的1-6-Michael / Michael加成反应,其中2-silyloxyfuran被成功地用作亲核试剂和亲电试剂顺序。这种方法与随后的还原相结合,可在温和的反应条件下以高收率轻松获得生物学上重要的稠合哌啶/丁内酯骨架,并且具有非对映选择性。
