A Convenient Synthesis of Δ7,8-Morphinan-6-one and Its Direct Oxidation to 14-Hydroxy-Δ7,8-morphinan-6-one
摘要:
Synthesis of Delta(7,8)-morphinan-6-one by Grewe cyclization and bromoketalization reaction as crucial steps is described. Introduction of a hydroxyl group at 14-position is demonstrated by direct oxidation with MnO2 in the presence of silica gel. (C) 2002 Elsevier Science Ltd. All rights reserved.
