摘要
研究了2-氨基-2'-羟基-1,1'-联萘衍生的有机小分子催化剂催化的直接羟醛缩合反应.以丙酮为反应物时最好,得到了99%的收率.以环酮为底物时,最高得到99∶1的非对映选择性,89%的对映选择性.
The direct aldol reactions catalyzed by organocatalyst derived from 2-amino-2'-hydroxy-1,1'- binaphthyl were studied. Up to 99% yield was obtained for acetone. Up to 99 : 1 anti : syn selectivity and 89% enantioselectivity were obtained for cycloalkanones.
