摘要

Abstract Various aryl carboxamides with alkoxy substituents at the ortho-position, applicable as direct intermediates toward novel ligands, were synthesised via aminocarbonylation of aryl-iodides (2-iodoanisole, 5-chloro-7-iodo-8-methoxy-quinoline, and 5-chloro-7-iodo-8- benzyloxy-quinoline) in the presence of in situ generated palladium (0) catalysts. Simple primary and secondary amines as well as aminoacid esters were used as N-nucleophiles. ...
