ABSTRACT An efficient catalyst-free microwave-assisted synthesis of tetrasubstituted pyrroles using dialkyl acetylenedicarboxylates and substituted monophenacylanilines has been developed. Axial chirality has been noticed in some N-(α-naphthyl/2-isopropylphenyl)-2,3-dicarbethoxy-4-arylpyrroles, but not with N-aryl-2,3-dicarbethoxy-4-(α-naphthyl)pyrrole. GRAPHICAL ABSTRACT
摘要已开发出一种使用二烷基乙炔二羧酸酯和取代的单苯甲酰苯胺的四取代吡咯的高效无催化剂微波辅助合成。一些 N-(α-naphthyl/2-isopropylphenyl)-2,3-dicarbethoxy-4-arylpyrroles 有轴向手性,但 N-aryl-2,3-dicarbethoxy-4-(α-naphthyl)pyrrole 没有. 图形概要
