preparation of amides starting from azides and enolisable aldehydes. The reaction proceeded via the formation of triazoline intermediates that were converted into amides via Lewis acid catalysis. Preliminary studies on the preparation of triazolines under chiral phase transfer catalysis are also presented, demonstrating that enantioenriched amides could be prepared from achiral aldehydes in moderate to low
在本文中,我们报告了从
叠氮化物和可烯化醛开始制备酰胺的两步过程。反应通过形成三唑啉中间体进行,该中间体通过
路易斯酸催化转化为酰胺。还介绍了在手性相转移催化下制备三唑啉的初步研究,表明可以从中等至低对映选择性的非手性醛制备对映体富集的酰胺。
