Enantioselective vicinal bis-acylation of olefins

A two-step sequence for the asymmetric vicinal acylation of olefins by a [2+2+1] strategy is reported. The key reaction is a [2+2] cycloaddition of an olefin to a chiral keteniminium salt derived from N-tosylsarcosinamide. This is followed by a regioselec

Asymmetric vicinal acylation of olefins: A new approach to enantiomerically pure γ-lactones

Amide 3 derived from N-tosylsarcosine and (2R,5R)-dimethylpyrrolidine was converted into keteniminium salt 4 which readily cycloadded to olefins. Hydrolysis of the adducts yielded cyclobutanones which were regiospecifically oxidized to γ-lactones 7. High
