Described herein is the development of an unprecedented approach to construct multiple heterocycles with high selectivity through Rh(III)-catalyzed two- or three-component cyclization reaction from simple and readily available starting materials: -methoxybenzamides, 2-butyne biscarbonate, and maleimides. This methodology provides an efficient strategy for the synthesis of diverse and complicated heterocycles in a one-pot manner and displays excellent features of extremely mild reaction conditions, easy operation, excellent regioselectivity, and good functional group compatibility.
本文描述了一种前所未有的方法的发展,通过 Rh(III)-催化的二或三组分环化反应,从简单易得的起始原料 - 甲氧基苯甲酰胺、2-丁炔二羧酸酯和马来酰亚胺中,高选择性地构建多种杂环。这种方法为一锅法合成各种复杂的杂环提供了一种有效的策略,具有反应条件非常温和、操作简单、区域选择性好、官能团兼容性好等特点。
