The efficient aza‐Michael additions of isatins to 2‐arylidene‐1,3‐diphenylpropan‐1,3‐diones at room temperature in the presence of cesium carbonate are described. The salient features of this protocol are no transition‐metal catalysts, mild conditions, high regioselectivity, high atom economy, satisfactory yield and simple work‐up procedures.
描述了在存在碳酸铯的情况下,在室温下将靛红有效地添加到2-亚芳基-1,3-二苯基丙烷-1,3-二酮中的aza-Michael。该方案的主要特点是无过渡金属催化剂,温和的条件,高区域选择性,高原子经济性,令人满意的产率和简单的后处理程序。
