We have developed an organocatalytic asymmetric Michael reaction of acylsilane through the selection of acylsilane substrates and organocatalysts, thus creating a rare example of acylsilane α-alkylation with a chiral guanidine catalyst, which afforded products in good yields and high stereoselectivity. The corresponding adducts described here have also been demonstrated to be useful in the synthesis
通过选择酰基硅烷底物和有机催化剂,我们开发了酰基硅烷的有机催化不对称迈克尔反应,从而创造了一个罕见的手性胍催化剂进行酰基硅烷α-烷基化的例子,该产物能够提供高收率和高立体选择性。还已经证明,在此描述的相应的加合物可用于合成非天然氨基酸和生物活性化合物。
