Abstract

The reaction of alkynyl carboxylic acids, glyoxylic acid derivatives, and amines in the presence of a copper catalyst afforded the corresponding propargyl amines in good yields. The alkynyl carboxylic acid of this coupling reaction shows similar reactivity to that of a terminal alkyne, and the reactivity of the glyoxylic acid is almost identical to that of an aldehyde. When 2‐aminopyridine was employed as the amine source, imidazopyridine derivatives were formed in good yields.
