Abstract

The beta-oxo thiosulfines 8, generated by ‘unzipping' of the corresponding acetyl alpha-chloroalkyl disulfides 11 with morpholine, are partially converted into the corresponding thioketones 12 which then cycloadd to 8 to give the observed cis- and trans-1,2,4-trithiolanes 15. The unsymmetrical Diels-Alder dimerization of 12 plays only a minor role. The new heterocycles thus obtained have been characterized spectroscopically and by X-ray crystallography.
