HETEROCYCLES FROM CARBOHYDRATE PRECURSORS. PART 40. KINETIC AND THERMODINAMIC PRODUCTS OF KETALATION OF 1-C-SUBSTITUTED L-THREO-GLYCEROL: A REGIOSELECTIVE FORMATION OF 1,3-DIOXOLANES

The mode of ketalation of some L-threo-glycerols has been studied.The kinetic product has an α-terminal (dioxolane) ring.The formation of β (dioxane) ring was also detected.The thermodynamic product has an α-threo-(dioxolane) ring.The regioselectivity of
