Diastereoselective synthesis of 3,6-dihydro-2H-1,3,4- thiadiazines

Thionation of the benzil hydrazones 3 with Lawesson's reagent afforded the 3,6-dihydxo-2H-1,3,4-thiadiazines 4 by an intramolecular cyclisation. This reaction was shown to be diastereospecific and allowed the formation of the exo compounds 4b-e. When the homochiral SAMP-hydrazone 3f was used, the reaction afforded enantiomerically pure (4R,6R,9S)-4f.
