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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
