Isothiocyanates in the chemistry of heterocycles

“…Mercaptoacetic and mercaptopropionic acids furnished adducts with isothiocyanates which were manipulated to yield thiazolidine and thiazine derivatives, respectively.1 The condensation of an isothiocyanate with 2-aminothiophenol was supposed to produce a dithiocarbamate which in turn furnished 2-aminobenzothiazole. 150 But this reaction could also proceed through the thiourea intermediate.…”
