hetero-Michael reactions among various oxygen, sulfur, and nitrogen nucleophiles and α,β-unsaturated compounds were carried out in the presence of catalytic amounts of o-benzenedisulfonimide as Brønsted acid organocatalyst. The reaction conditions were very mild, and the yields of target products were good. The catalyst was easily recovered and purified, ready to be used in further reactions. This ability
摘要 各种氧、硫、氮亲核试剂与α,β-不饱和化合物之间的杂迈克尔反应是在催化量的邻苯二磺酰亚胺作为布朗斯台德酸有机催化剂存在下进行的。反应条件非常温和,目标产物收率良好。催化剂很容易回收和纯化,准备用于进一步的反应。这种能力赋予经济和生态优势。补充材料可用于本文。转至出版商的 Synthetic Communications® 在线版以查看免费的补充文件。图形概要
