A stereoselective synthesis of ethyl 9-cis-7,8-didehydro-19-trifluoromethylretinoate
摘要:
The design and synthesis of ethyl 9-cis-7,8-didehydro-19-trifluoromethylretionate was described. The key step is the Sonogashira reaction of ethyl 3-iodo-4,4,4-trifluoro-2(Z)-butenoate 2 with terminal alkyne 3. (C) 2000 Elsevier Science S.A. All rights reserved.
