Abstract

Synthesis of 2-(aminoacid ester)-3-(6-methyl-2-pyridyl)-3,4-dihydro-2-1,3,2λ5-benzoxazaphosphinin-2-thiones () was accomplished through a two-step process. It involves the prior preparation of 2-chloro-3-(6-methyl-2-pyridyl)-3,4-dihydro-2-1,3,2λ5-benzoxazaphosphinin-2-thione monochloride () and its subsequent reaction with the aminoacid ester hydrochlorides in dry tetrahydrofuran-toluene in the presence of triethylamine at various temperatures. These compounds were characterized by IR, 1H, 13C, 31P NMR and mass spectral data.
