reaction of aliphatic aldehydes, ketones, and alcohols catalyzed by L-proline. Steric effects on the reaction were studied with substituted ketones, aldehydes, and alcohols, and the results indicate that reactions employing methyl ketones, α-unsubstituted aliphatic aldehydes and methanol produce the β-alkoxy ketones in the best yields when L-proline is used as the catalyst. The reaction mechanism is discussed
L-脯氨酸催化脂肪醛、酮和醇的一锅三组分反应制备β-烷氧基酮。研究了取代酮、醛和醇对反应的空间位阻效应,结果表明,使用甲基酮、α-未取代脂肪醛和甲醇的反应以 L-脯氨酸为原料时生成 β-烷氧基酮的产率最高。催化剂。讨论了反应机理。
