KAl(SO4)2·12H2O is found to catalyze efficiently the stereoselective one-pot three-component cyclocondensation of homophthalic anhydride, aldehydes, and amines under mild conditions to afford the corresponding cis-isoquinolonic acids in good yields.
发现KAl(SO 4)2 ·12H 2 O在温和条件下能有效催化高选择性的邻苯二甲酸,醛和胺的立体选择性一锅三组分环缩合反应,从而以良好的收率提供相应的顺式-异喹啉酸。
