A new, facile method for the conversion of α,β-enone tosylhydrazones to the transposed allylic sulfides is described which combines sulfenylation of the hydrazone dianions with hydride reduction of the α′-sulfenylated hydrazones. This novel route to allylic sulfides can constitute the sequences for the two directionally different types of enone transposition with 1,2-carbonyl shift.
描述了一种将 α,β-烯酮甲苯磺酰腙转化为转位烯丙基硫化物的新方法,该方法将腙二价阴离子的磺基化与 α'-磺基化腙的氢化物还原相结合。这种烯丙基硫化物的新途径可以构成两种方向不同类型的具有 1,2-羰基移位的烯酮转座的序列。
