Abstract
Benzoylated glycine derivatives 1b - j are mixtures of isomers A and B (minor) due to slow rotation about the amidic N - C(CO) bond. A steri cally hindered rotation around the N - C(R) bond was also evidenced in some cases. Molecular mechanics study using MMX force field showed im portant differencies between the calculated and experimental relative stabilities of isomers A and B.
