文摘

The reaction of alkynylzirconates with 伪,尾-unsaturated carbonyl compounds has been achieved. Reactions of alkynylzirconates with cinnamates afford ester-functionalized multisubstituted dienes, in which the C3 attacks cinnamates via Michael addition. Reactions of alkynylzirconates with benzylideneacetone give (1E,3Z)-dienes, in which benzylideneacetone acts as an electrophile to afford a proton.
