Abstract

2-Substituted thiazolidines (IIIa-g) were prepared by the reaction of 2-alkylthiothiazolines (II) and active methylene compounds. The tetra-substituted double bonds of IIIa-g were resistant to catalytic hydrogenation. N-Halogenation of IIIb was effected by t-butylhypochlorite or bromine in methanol-chloroform. BF 3-etherate treatment of IIIb in acetic anhydride gave three products, VI, VII and VIII. This new method of furoxane formation was also applicable ...
