In the presence of a Brønsted acid catalyst, both aldehydes and N-Boc-aminals were converted to enecarbamates and N-Boc-iminium salts as activated nucleophiles and electrophiles, respectively, giving unprecedented Mannich adducts.
在Brønsted酸催化剂的存在下,醛和N-Boc-胺醇均被转化为烯基氨酸酯和N-Boc-亚胺盐,分别作为活化亲核试剂和电泳试剂,从而产生前所未有的Mannich加合物。
