Exposure of an enone to a catalytic quantity of [CuH(PPh3)]6 in the presence of one of several silyl hydrides (PhMe2SiH, PMHS, HMe2SiOSiMe2H) leads to conjugate reduction with concomitant formation of the corresponding silyl enol ether. Without isolation, treatment of these intermediates with a Lewis acid at low temperatures in the presence of an aldehyde, or with fluoride ion together with an activated
在几种硅烷氢化物(PhMe 2 SiH,PMHS,HMe 2 SiOSiMe 2 H)之一存在下,将烯酮暴露于催化量的[CuH(PPh 3)] 6会导致共轭还原并伴随形成相应的甲硅烷基烯醇醚。在不分离的情况下,在醛存在下在低温下用路易斯酸或氟化物离子与活化的卤化物一起对这些中间体进行处理,可在单次操作中获得良好的三组分偶联(3-CC)产物收率。反应瓶。
