发展了1,3-二炔的区域和立体选择性烯炔CM和RCM反应。烯二炔的闭环复分解反应诱导炔基钌卡宾物种的容易的金属向[1,3]-移位,从而为完全共轭的1,5-二烯-3-炔的合成提供了独特的入口。
The regio- and stereoselective enyne CM and RCM reactions involving 1,3-diynes have been developed. The ring-closing metathesis of enediynes induces a facile metallotropic [1,3]-shift of alkynyl ruthenium carbene species, thereby providing a unique entry into the synthesis of fully conjugated 1,5-diene-3-ynes.
