Ring contraction of 2-O-trifluoromethanesulphonates of α-hydroxy-γ-lactones to oxetane carboxylic esters

2-O-Trifluoromethanesulphonate esters of the four diastereomeric 3,5-di-O-benzyl-pentono-1,4-lactones gave, on treatment with potassium carbonate in methanol, efficient ring contraction to methyl oxetane-2-carboxylic esters. The stereochemistry at C-2 of
