In the presence of zinc naphthenate as the catalyst, the reaction of phenyl isocyanate with 1,2-propanediol and 3,4-O-isopropylidene-d-mannitol gave the primary phenylcarbamates in high yield. 1,2,6-Hexanetriol was selectively phenylcarbamoylated at O-1, and N6-benzyladenosine at O-2′. The common methyl aldohexo- and aldopento-pyranosides gave the 3-mono(phenylcarbamate)s in fair to excellent yields
