Described are synthetic sequences which effect allylic transformations I and II. Sequence I involves (1) conversion of a primary allyl alcohol into the corresponding N, N-dimethyl-amine oxide, (2) [2,3]-rearrangement to give an N, N-dimethylhydroxylamine and (3a) reduction to give the ‘rearranged’ secondary or tertiary allyl alcohol [e.g.36 35 37 40]. Sequence II involves the same steps (1) and (2)
描述了实现烯丙基转化I和II的合成序列。序列I涉及(1)将伯烯丙醇转化为相应的N,N-二甲基氧化胺,(2)[2,3]重排得到N,N-二甲基羟胺,(3a)还原得到N,N-二甲基羟胺“重排”的仲或叔烯丙醇[例如36 35 37 40 ]。序列II涉及相同的步骤(1)和(2),随后是(3b)仲N,N-二甲基-羟胺的N-甲基化和(4)霍夫曼消除以得到乙烯基酮[例如。11 12 13 14 15 ]。
