The diastereoselective reactions of chiral seven-membered-ring enolates have been systematically investigated. Diastereoselectivity was found to be general for ϵ-lactams, ϵ-lactones, and cycloheptanones with various substituent patterns. Computational investigations provided insight into the origin of the diastereoselectivity. A model for predicting the stereochemistry of seven-membered-ring enolate
手性七元环烯醇化物的非对映选择性反应已被系统研究。发现对于具有各种取代基模式的ε-内酰胺、ε-内酯和环庚酮来说,非对映选择性是普遍的。计算研究提供了对非对映选择性起源的深入了解。提出了预测七元环烯醇化物烷基化立体化学的模型。
