[reaction: see text] Lithium eneselenolates generated from selenoamides underwent Michael addition to alpha,beta-unsaturated esters and ketones with high diastereoselectivity to give delta-oxo selenoamides in moderate to high yields within a few seconds. Further selective transformations of the delta-oxo selenoamides were also achieved.
[反应:见正文]从硒代酰胺中生成的烯硒酸锂经过迈克尔加成反应后,具有高非对映选择性的α,β-不饱和酯和酮,可在几秒钟内以中等至高收率得到δ-氧代硒代酰胺。还实现了δ-氧代硒代酰胺的进一步的选择性转化。
