发展了一种从α,β-不饱和醛和炔醛出发来获取α-乙烯基-β-炔基取代的烯醛的新绿色合成路线. 该方法体现出较为广泛的底物适用范围, 且反应条件温和. 此外, 还对反应过程中共轭-羟醛缩合的催化过程进行了详细讨论.

关键词: α-乙烯基-β-炔基取代的烯醛, 共轭-羟醛缩合, 有机催化, 烯胺

A new green synthetic route to α-vinyl β-alkynyl enals from α,β-unsaturated aldehydes and ynals is developed. This protocol allows a broad substrate scope and mild conditions. Furthermore, a proposed mechanism of a deconjugation-aldol condensation process is discussed in detail.

Key words: α-vinyl β-alkynyl enal, deconjugation-aldol condensation, organocatalysis, enamine
