[reaction: see text] An asymmetric total synthesis of (-)-swainsonine and (+)-6-epicastanospermine is described from a common intermediate, which is obtained through diastereoselective [2 + 2] cycloaddition of dichloroketene to a chiral enol ether.
[反应:见正文]从一个常见的中间体中描述了一种不对称的(-)-swainsonine和(+)-6-二十碳精胺的合成,该中间体是通过将二氯乙烯酮非对映选择性[2 + 2]环加成手性烯醇醚制得的。
