approaches to the key (−)-(2R)-cis-tosylate 1 and its (+)-(2S)-enantiomer 15 via generation of chiralimideenolates having a 2,2-disubstituted olefin functionality in the β-position, are described. In a “protecting group free” sequence, reaction of the titanium enolate generated from (4R)-benzyl-2-oxazolidinone derived imide 5b with s-trioxane provided a convenient intermediate 19 which could be directly
