title: Syntheses of 3-O- and 6-O-propanoylmorphine--a reinvestigation and correction.
abstract: 3-O-Propanoylmorphine was obtained using the conditions reported earlier for the specific synthesis of 6-O-propanoylmorphine. The latter isomer was synthesized using two different methods; the two compounds were authenticated using IR, MS, carbon-13 and proton NMR.
