Abstract

A palladium-catalyzed regioselective three-component cascade reaction of carbon dioxide, amines and allenes has been developed, providing an expedient and practical method for the construction of a range of functionalized carbamates containing dihydrobenzofuran or indole moiety in moderate to excellent yields. The broad substrate scope, good functional group tolerance and excellent chemo- and regioselectivity are the features of the transformation.

钯催化的二氧化碳，胺和烯丙基的区域选择性级联反应，用于合成功能化的氨基甲酸酯

摘要

已经开发了二氧化碳，胺和丙二烯的钯催化的区域选择性三组分级联反应，提供了一种方便实用的方法，可用于以中等至优异的产率构建一系列含有二氢苯并呋喃或吲哚部分的官能化氨基甲酸酯。广泛的底物范围，良好的官能团耐受性以及出色的化学和区域选择性是转化的特征。
