REGIOSELECTIVE (PHENYLCARBAMOYL)ATION OF POLYHYDROXY COMPOUNDS BY PHENYL ISOCYANATE-ZINC NAPHTENATE

Nishino, Shigeyoshi,Ishido, Yoshiharu

, p. 161 - 174 (2007/10/02)

In the presence of zinc naphtenate as the catalyst, the reaction of phenyl isocyanate with 1,2-propanediol and 3,4-isopropylidene-D-mannitol gave the primary phenylcarbamates in high yield. 1,2,6-Hexanetriol was selectively phenylcarbamoylated at O-1 and
