The racemic total synthesis of elegansidiol, farnesiferol B, and farnesiferol D has been obtained following a Diels-Alder approach. Gillman addition, cross metathesis reaction are the other key steps involved in the target synthesis. (C) 2010 Elsevier Ltd. All rights reserved.
The Concise Synthesis of a Key Intermediate for the Total Synthesis of Fumagillin, TNP-470, and Ovalicin
The facile synthesis of a key intermediate for the total synthesis of the antiangiogenic compound fumagillin, its semisynthetic analogue TNP-470, and ovalicin is described. The methodology employs a Diels-Alder strategy and a zinc-mediated ring-opening reaction to realize the cyclohexane backbone.
