Rt. Brown et al., SYNTHESIS OF MORPHINE-6-GLUCURONIDE VIA A HIGHLY SELECTIVE ENZYME-CATALYZED HYDROLYSIS REACTION, Tetrahedron letters, 36(7), 1995, pp. 1117-1120
Morphine-6-glucuronide 1, a patent analgesic, has been prepared from m
orphine-3,6-diglucuronide 3 via a highly selective hydrolytic cleavage
of the phenolic 3-glucuronide group using beta-glucuronidase as catal
yst.
