N-formyl aza-heterocycles 15-24 can be prepared by Ra-Ni desulfurization of thiazolidine derived polycyclics 5-14 which in turn are obtained by intramolecular thiono α-acyliminium cyclisations of ?-nucleophiles.
Stereoselective synthesis of heterocycles by desulfurisation of condensed thiazolidin-2-ones
Hamersma,Speckamp
, p. 2861 - 2866 (2007/10/02)
Elimination of the S atom in fused thiazolidines e.g. 7 or 9 has been investigated using three methods. Whereas LAH reduction gave the corresponding thiazolidines and H2O2/HCOOH oxidation the S,S-dioxides both types of compound could
