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
The opticalresolutions of various alcohols as phenylcarbamates were examined by HPLC on chiral stationary phases derived from sixteen cellulose tris(phenylcarbamate) derivatives. The optical resolving power of chiral stationary phases was greatly influenced by substituents on the phenyl groups of the cellulose derivatives. Also, cellulose tris(3,5-dimethylphenylcarbamate) could very efficiently resolve
