Abstract:
Reaction of 3-aryl-1-(3,4,5-trimethoxyphenyl)prop-2-yn-1-ones with (+)-pseudoephedrine leads to products of alkyne moiety cleavage, namely, 1-(3,4,5-trimethoxyphenyl)ethanone and N-(1-hydroxy-1-phenylprop-2-yl)-N-methylbenzamides. In the course of the process one of alkyne carbons undergoes a formal reduction to a Me group, whereas the other one is oxidized to a C(O)NRR’ moiety.
