| Abstract: | In the reactions of acetylthioacetanilides ( 1a–c ) and diacetylthioacetanilides ( 3a–f ) with phosgene 1,3-thiazetidine-2-one ( 2a–c ) and 1,3-oxazine-2-one ( 5a–f ) were obtained respectively. The structures of new compounds were elucidated by elemental analyses, i.r., 1H-n.m.r., m.s., for 1d–f by 19F-n.m.r. and for 2a and 5a by 13C-n.m.r. spectral data. |
