sequential treatment of an acetylide with a Fischer carbene complex and an alkene/diene yields alkynylcyclopropanes with a wide substitution range. The intramolecular process provides 1‐alkynylbicyclo[3.1.0]cyclohexanes by starting from 1,6‐enynes. A non‐heteroatom‐stabilized metal alkynylcarbene is responsible for the selective transfer of the propargylene unit.
Fis(c)可以环化!用费歇尔卡宾配合物和烯烃/二烯对乙炔进行顺序处理,得到的炔基环丙烷具有较宽的取代范围。分子内过程从1,6-烯炔开始提供1-炔基双环[3.1.0]环己烷。非杂原子稳定的金属炔基卡宾负责丙烯炔单元的选择性转移。
