✦ Synopsis

Bis(imin0)thietanes 1 are accessible by two methods developed in our laboratory: (i) (3 + 1)-cycloadditions of N-sulfonyl substituted thiiranimines with isonitriles, and (ii) ( 2 + 2)-cycloadditions of sulfonyl isothiocyanates with ketenimines.' An interesting feature of 1 is the presence of a thioimidate function adjacent to an extra imine function which offers the possibility of carrying out ring-transformation reactions as shown below.

In one of the rare published examples on the title reaction, Cook and coworkers' reported on the Dimroth rearrangement2 of the 5-aminothiazole 1 to the dithiohydantoin 2 followed by mild oxidation to an orange product (mp 270") having structure 2. We have re-examined this reaction and have come to d
