Abstract
3-Aryl-2-bromopropanoic acid esters reacted with o-phenylenediamine, 2-sulfanylaniline, and L-cysteine to give quinoxaline, 1,4-thiazine, and thiomorpholine derivatives, respectively, containing an arylmethyl substituent. Analogous 1,4-benzoxazine derivatives were synthesized by reactions of 3-aryl-2-bromopropanoyl chlorides with 2-aminophenol or 2-methoxyaniline.
