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 aryl-methyl substituent. Analogous 1,4-benzoxaz

Reaction of 3-aryl-2-bromopropanoic acids esters, products of the Meerwein arylation, with sodium azide afforded alkyl 2-azido-3-arylpropanoates. The latter react with ethyl acetoacetate and phenylacetylene to form 1,2,3-triazole derivatives. A one-pot me

Two synthetic pathways for the preparation of 2-mercapto-3-arylpropanoic acids were developed. First, by the reaction of arenediazonium bromides with acrylic esters in the presence of CuBr, alkyl (2-bromo-3-aryl)propanoates were formed. Their cyclization with thiourea produced 5-(R-benzyl)-2-imino-4- thiazolidinones, which yielded 3-aryl-2-mercaptopropanoic acids by alkaline hydrolysis. Second, direct Meerwein arylation of acrylates in the presence of S-nucleophile (NaSH) allowed isolation of 3-phenyl-2-mercaptopropanoic acid in 8% yield. Such acids were used for cyclization with cyanoguanidine and phenyl isothiocyanate yielding 1-[5-(R-benzyl)-4-oxo-1,3-thiazolidin-2-ylidene] guanidines and new 5-(R-benzyl)-3-phenyl-2-thioxo-1,3-thiazolidin-4-one (rhodanine) derivatives correspondingly.

Synthesis of heterocycles on the basis of arylation products of unsaturated compounds. 11.1 5-R-benzyl-2-iminoselenazolidin-4-ones from ethyl 3-aryl-2-bromopropanoates

Ethyl 3-aryl-2-bromopropanoates 2a-p were prepared by reaction of ethyl acrylate with arenediazonium bromides 1a-p in the presence of CuBr (Meerwein arylation). These compounds react with selenourea to form 5-R-benzyl-2- iminoselenazolidin-4-ones 4a-p. Compounds 4a-p hydrolyze into the corresponding selenazolidin-2,4-diones.
