Reaction of 4-isopi-opylamiiio-5-chloro-1,2-dithiole-3-oiies 3 and S2Cl2 in acetonitrile gave selectively 3-oxo-bis[1,2]dithiolo[1,4]tliiazine-5-tiliones I by the addition of triethylamine and bis[1,2]dithiolo[1,4]thiazine-3,5-diones 5 under the action of formic acid. 3,5-Diones 5 were also obtained by intramolecular cyclization of N,N-bis(5-chloro-3-oxo[1,2]dithiol-4-yl)amines 6 with S,Cl, in the presence of Et3N.

A diverse library of bis[1,2]dithiolo[1,4]thiazines and bis[1,2]dithiolopyrrole derivatives were prepared for evaluation of activity against the nucleocapsid protein of the Feline Immunodeficiency Virus (FIV) as a model for HIV, using an in vitro cell culture approach, yielding nanomolar active compounds with low toxicity.
