✦ Synopsis

1,3-Thiazepines. Part 2. Reaction of 2-Iminohexahydrothiazepines with Phenyl Isocyanate and Isothiocyanates.

-Reaction of the iminothiazepines (I) with phenyl isocyanate (II) gives the expected ureas (III) in good yields. In contrast, reaction with aryl isothiocyanates in refluxing toluene produces only substitution products (cf. (V)). Under more mild conditions (acetone, room temperature), unexpectedly substituted thioureas are obtained, e.g. compound (VII)/(VIII).
