我们开发了一种灵活的方法,能够在 BF 3 ⋅ Et 2 O 的存在下,在钯或铜催化下获得高度官能化的吡咯。这种催化方法利用市售胺作为反应伙伴,具有广泛的范围、可扩展和友好的操作仅产生水作为副产品。该协议的普遍性通过一系列二、三、四和五取代吡咯的成功制备得到证明。该方法适用于生物活性化合物的合成和衍生化。
developed for the synthesis of substituted pyrrole derivatives from propargylic acetates, enoxysilanes and primary amines. Various aromatic and aliphatic propargylic acetates participate well in the reaction, providing the propargylation/amination/cycloisomerization products in good yields with complete regioselectivity. The one-pot multicomponent coupling reaction furnishes substituted pyrroles in high

A convenient and general approach towards the synthesis of substituted pyrroles from propargylic acetates, silyl enol ethers, and primary amines was described. This novel transformation was catalyzed by indium trichloride in a one-pot synthesis, and high yields of various pyrrole derivatives were obtained.
Efficient synthesis of highly substituted pyrroles based on the tandem reactions: intermolecular amination and Pd(II)-catalyzed intramolecular hydroamidation
A novel and efficient method for construction of polysubstituted pyrroles, which included an intermolecular amination and Pd(II)-catalyzed intramolecular hydroamidation, was developed. It was found that the reactions gave high yields (55-92%). Crown Copyright (C) 2008 Published by Elsevier Ltd. All rights reserved.
