- Synthesis of Bridgehead-Bridgehead Substituted Bicycloalkanes
-
A convenient synthetic route to several bicycloalkanes bearing substitution at both bridgehead positions is described.The two-step procedure, which involves alkylation of the monoenolates of readily available cyclohexane diesters with 1,2-dihaloethane followed by a base-inducted cyclization of the derived haloethylated product, was successfully applied to the synthesis of dimethyl bicyclooctane-1,4-dicarboxylate, dimethyl bicycloheptane-1,4-dicarboxylate and dimethyl bicyclooctane-1,5-dicarboxylate.Additionally, it was found that the two latter diesters could be obtained in quite acceptable yields in a one-pot procedure through their corresponding cyclohexyl bisenolate precursors.
