A [2,3]-Wittig rearrangement that requires severe deformation from a stable 6-membered ring chair structure and its application to synthesize 1,3-anti-3,5-anti-1,3,5-trimethylated carbon chain compounds

Abstract

Abstract A [2,3]-Wittig rearrangement was accomplished overcoming severe six-membered ring deformation barrier and utilized as a key step in a highly stereoselective synthesis of the title compounds.
