anti-3-amino-1-alken-4-ols 11 and 14. Alternatively, reaction of imines 13a, 13f, and 13g with trifluoromethanesulfonic anhydride and acidic methanol gave, via rearrangement, double inversion, and hydrolysis, the isomeric anti-4-amino-1-alken-3-ols 22, 38a, and 38b in good yield. The stereochemistry of the rearrangement products has been established by a single crystal X-ray study of compound 37 and by chemical correlation
烯丙基硼烷试剂9和12与醛的缩合得到具有相对和绝对立体控制较高的抗-3-[((二苯基亚甲基)氨基] -1-烯烃-4-醇10和13。随后的脱保护得到相应的游离抗-3-氨基-1-烯烃-4-醇11和14。或者,亚胺13a,13f和13g与三氟甲磺酸酐和酸性甲醇的反应通过重排,两次转化和水解得到。 ,异构体抗4-氨基-1-链烯-3-醇22、38a和38b的收率很高。通过化合物37的单晶X射线研究和化学相关性确定了重排产物的立体化学。
