1.3- Oxathiolylium

Diaryl derivatives of the 1,3-oxathiolylium system (29) are prepared by acid-catalyzed cyclization of the /3-keto thioesters (28) which are readily prepared from thioacid salts (27)... [Pg.114]

Oxathiolylium salts (317) condense with cyanamide in the presence of sodium ethoxide to give an open-chain intermediate (318) which cyclizes to substituted 4-aminothiazoles (319 Scheme 211) (73JPR497). [Pg.305]
