Abstract
Abstract The one-pot, four-component tandem reaction of ethyl 2-[(2-oxo-2-arylethyl)sulfonyl]acetate/ethyl 2-[(2-ethoxy-2-oxoethyl)sulfonyl]acetate, an aromatic aldehyde and pyrrolidine provides a rapid and facile access to new ethyl 3-aroyl-1-benzyl-2,2-dioxo-4-aryloctahydro-2-pyrrolo[2,1-c][1,4]thiazine-1-carboxylates/diethyl 1-benzyl-2,2-dioxo-4-aryloctahydro-2-pyrrolo[2,1-c][1,4]thiazine-1,3-dicarboxylates. This reaction shows high stereoselectivity and proceeds in good yields.
