An effective aza-Mannich reaction between olefinic rhodanines/hydantoins and N-Boc aminals catalyzed by Brønsted acid has been developed. Multifunctional rhodanine/hydantoinderivatives were obtained in 71–86% yields and an up to 95/5 Z/E ratio under mild conditions.
已经开发了由布朗斯台德酸催化的 烯烃若丹宁/乙内酰脲与N- Boc缩醛之间的有效氮杂-曼尼希反应。在温和条件下,以71-86%的产率获得了多功能的若丹宁/乙内酰脲衍生物,其收率高达95/5 Z / E。
