First total synthesis of 7(S),17(S)-Resolvin D5, a potent anti-inflammatory docosanoid
摘要:
The first total synthesis of 7(S),17(S)-Resolvin D5, a lipid mediator derived from docosahexacnoic acid, has been achieved. The chiral centers were generated via a Co-salen hydrolytic kinetic resolution of a terminal epoxide with > 99% ee. Key steps include Takai olefination, Pd-0/Cu-I coupling and simultaneous deprotection and ester cleavage with lipase from Candida rugosa. (c) 2005 Elsevier Ltd. All rights reserved.
