1-NORBORNYLLITHIUM AS A PRECURSOR FOR THE SYNTHESIS OF NOVEL ORGANIC 1-BICYCLO[2.2.1]HEPTANE DERIVATIVES AND FOR THE IMPROVED PREPARATION OF 1-CHLORO-BICYCLO[2.2.2]OCTANE

An improved strategy for synthesis of 1-chloro-bicyclo[2.2.2]octane is described in which the key compounds 1-norbornyl substituted ethyl formate (3) or 1-norbornylcarbaldehyde (7) were prepared from 1-norbornyllithium (1). The latter appeared as a useful precursor for the synthesis of various organic bridgehead substituted derivatives.
