| Abstract: | The reaction of acrylic acid with 2-aminothiophenol gives 5-carboxyethyl-2,3-dihydro-5H-benzob]1,4]-thiazepin-4-one and
N-2-(carboxyethylthio)phenyl]-α-alanine, while the reaction of acrylic acid with bis(2-aminophenyl) disulfide gives bis2-(carboxyethylamino)phenyl]
disulfide. The action of potassium thiocyanate in acid medium on the carboxyethylamino derivatives yields 1-2-carboxyethylthio)phenyl]dihydro-4(1H,3H)-pyrimidinone-2-thione,
bis-{2-dihydro-4(1H, 3H)-pyrimidinone-2-thion-1-yl]phenyl} disulfide, and 3-(2-mercaptobenzothiazol-3-yl)propanoic acid.
