Reaction of cyclic diazoamides with furan systems using rhodium(II) acetate as a catalyst afforded a variety of (3Z)-3-[(2E)-4-oxopent-2-en-1-ylidene]indol-2-ones in a regio- and diastereo-selective manner. The diastereoselectivity was based on the flow rate of cyclic diazoamides. The representative products were characterized by single-crystal X-ray analyses.
环状重氮酰胺与呋喃体系的反应,使用乙酸铑(II)作为催化剂,得到各种(3 Z)-3-[(2 E)-4-氧戊二-2-烯-1-亚烷基]吲哚-2-酮以区域和非对映选择性的方式。非对映选择性是基于环状重氮酰胺的流速。通过单晶X射线分析表征代表性产物。
