Thiazolidine-2-thiones can be prepared with complete control over stereochemistry from the olefins (134). Addition of iodoiso-cyanate to the olefins in MeOH generates the known B-iodocarbamates (I35) which on treatment with potassium ethyIxanthate followed by base give the thlazolidine (136). The opposite stereoisomer (138) is formed by addition of the xanthate to the azlrldine (137) formed from base treatment of (135). ... 

Comparatively speaking, the preparation of xanthate ester is simple. For example, xanthate ester can be produced by adopting xanthate and chloroalkene as feeds. And cyanate ester can be produced by adopting xanthate and vinyl cyanide as feeds. The related reactions are as follows ...
