Evaluation of 'east-to-west' ether-forming strategies for the total synthesis of maoecrystal V

Tetrahedron Lett. 2013 Feb 13;54(7):635-637. doi: 10.1016/j.tetlet.2012.11.135.

Abstract

Model systems that evaluated different approaches to construct the central ether ring of maoecrystal V are described. Our first model systems attempted the ether formation using C-H functionalization reactions, which led to interesting rearrangements but none of the desired ether product. An intramolecular conjugate addition strategy was then explored that successfully formed the targeted C-O bond but resulted in the undesired stereochemistry.
