An enantioselective ring-expanding cycloisomerization of 1,5-enynes bearing a cyclopropylidene moiety has been developed. This methodology provides a new approach to bicyclo[4.2.0]octanes, a structural motif present in many biologically active natural products.
一种含有环丙基部分的 1,5-烯炔的对映选择性环扩张环化反应已经被开发出来。这种方法为双环[4.2.0]辛烷提供了一种新的合成途径，双环[4.2.0]辛烷是许多生物活性天然产物中存在的结构基序。
