1,2‐Elimination of optically‐active vinyl sulfoxide‐allylic acetates led to corresponding allenynes in excellent yields. When the chirality of the sulfinyl group "matched" that at the allylic position, the chirality at the allylic stereogenic center could be efficiently transferred to the allenic axis.
1,2-消除光学活性乙烯基亚砜-烯丙基乙酸酯可产生相应的烯炔,收率很高。当亚磺酰基的手性与烯丙基位置的手性“匹配”时,可以将烯丙基立体中心的手性有效地转移至烯丙基轴。
