摘要

766 whereas medium and large rings produce only moderate diastereomeric ratios [(8), n= 7, 8, 15,< 2: 1]. Such selectivities have been explained in terms of an electronic interaction between the 0* orbital of the incipient bond and the adjacent high energy CS a bond. 3 In open chain molecules and presumably in very large rings, this is the same as Felkin's model, S with the mediumsized group [the ring for (11») adjacent to the carbonyl group ...
