Reactions of polyfluorocarbonyl compounds and their trifluoroacetylimines with fused heterocycles

C-Hydroxy- andC-aminoalkylation of iminodibenzyl, iminostilbene, phenoxazine, and phenothiazine with hexafluoroacetone, methyl trifluoropyruvate, and their trifluoroacetylimines were investigated. The substitution occurred at one or severalpara- andortho-positions to the N atom of the heterocycles. In the case of methyl trifluoropyruvate and its derivative the substitution in theortho-position was accompanied by the formation of lactams.Translated fromIzvestiya Akademii Nauk.
