This paper describes a base-catalyzed domino reaction of electron-deficient enynes with malonate-derived α,β-unsaturated esters and ketones, which provides a rapid, stereoselective access to multi-functionalized cyclopentanes and inden-5(6 H)-ones in high yields. In this reaction, the alkynyl group of the enyne acts as an activating group rather than a reacting group.
本文描述了缺电子的炔烃与丙二酸酯衍生的α,β-不饱和酯和酮的碱催化的多米诺反应,该反应可快速,立体选择性地接入多官能团的环戊烷和inden-5(6 H)-ones。高产。在该反应中,烯炔的炔基充当活化基团而不是反应基团。
