A sequential RCM/fragmentation protocol towards chiral, stereodefined medium ring sesquiterpenoids. A carvone route to E- and Z-germacrenes
摘要:
A short, flexible and enantioselective approach towards 10-membered germacratrienones, from the commercially available monoterpene chiron (-)-carvone, involving RCM and Grob-type fragmentation as the pivotal steps is delineated. (c) 2005 Elsevier Ltd. All rights reserved.
