Diastereoselective asymmetric thio-Claisen rearrangement has been carried out by the reaction of thioamides with allyllic bromide (Scheme 37). Thioamide dianions (generated by the highly efficient reaction of A -benzyl thioamides with 2 equiv. of BuLi) take place alkylation, allylation and silylat-ion selectively at the carbon atom adjacent to the nitrogen atom of the thioamide dianions (Scheme 38). ... [Pg.159]
