Reaction Steps
Starting from a 5α-alkoxymethyl-2β,4α-dihydroxy-cyclopentyl-1β-acetic acid-γ-lactone, wherein the alkoxy group is a methoxy, benzyloxy and p-methoxybenzyloxy group, esterification in pyridine with 1.3 molar equivalents of both acetic, acetic-formic or propionic anhydride and benzoyl or p-phenylbenzoyl chloride, gave the 4α-formate, acetate, m.p. 76°-77°, [α]D = - 29.5°, [α]365° = - 74°(CHCl3), propionate, benzoate and p-phenylbenzoate.
