摘要

A novel synthesis of Hantzsch-type N-substituted 1, 4-dihydropyridines from salicaldehydes, ethyl propiolate, and amines has been developed. Salicaldehydes were treated with ethyl propiolate in the presence of N-methylmorpholine to give ethyl 3-(2-formylphenoxy) propenoates. Three equivalents of ethyl 3-(2-formylphenoxy) propenoates reacted with 1 equiv of amines under trifluoroacetic acid (TFA) catalyst to furnish the corresponding N- ...
