synthesising symmetrical and non-symmetrical 3,4-diaryl-substituted pyrroles is proposed, consisting of (i) the condensation reaction between phenylacetonitriles and aldehydes to give acrylonitriles, (ii) the conjugate addition of cyanide to afford succinonitriles, and (iii) reduction of the succinonitriles with DIBAL-H to provide the target pyrroles in good overall yields. The implementation of this technology
提出了一种合成对称和非对称 3,4-二芳基取代吡咯的简单方法,包括 (i) 苯乙腈和醛之间的缩合反应得到丙烯腈,(ii) 氰化物的共轭加成得到丁二腈,和(iii) 用 DIBAL-H 还原丁二腈,以良好的总产率提供目标吡咯。介绍了该技术用于制备层状蛋白 R 的实施。
