Abstract

Recently we have reported several synthetic approaches to branched triangulanes (oligoepiroalkanes consisting only of three-membered rings). lI2 Unfortunately, most of these are rather complicated multistep syntheses. The most convenient approach is based on a methodology previously used in the synthesis of unbranched triangulane~, 39~ ie cycloaddition of (chloromethy1) carbene to an appropriate bicyclopropylidene, 6 ...
