RING CONTRACTION OF 2-O-TRIFLUOROMETHANESULFONATES OF ALPHA-HYDROXY-GAMMA-LACTONES TO OXETANE CARBOXYLIC ESTERS
2-O-Trifluoromethanesulphonate esters of the four diastereomeric 3,5-di-O-benzyl-pentono-1,4-1actones gave, on treatment with potassium carbonate in methanol, efficient ring contraction to methyl oxetane-2-carboxylic esters. The stereochemistry at C-2 of the resulting oxetanes is determined largely...
