In the presence of a catalytic amount of trityl salt, α,β-acetylenic ketones react with silyl enol ethers to afford the corresponding aldol adducts (1,2-addition products) stereoselectively in high yields. Naturally occurring monoterpenes, trans- and cis-tagetones, are synthesized by the use of this reaction.
在催化量的三苯甲基盐存在下,α,β-炔酮与甲硅烷基烯醇醚反应以高产率立体选择性地提供相应的羟醛加合物(1,2-加成产物)。天然存在的单萜、反式和顺式-万寿菊内酯是通过使用该反应合成的。
