C3 epimerization and selective C2C3 bond fission of alkyl chrysanthemate

Abstract Treatment of alkyl chrysanthemate with Lewis acid leads to C 3 epimerization, while protonic acid treatment gives rise to selective C 2 C 3 bond cleavage. The latter method is successfully applied to the synthesis of optically active tetrahydrolavandulol.

Preparation of solid superbase catalyst and its application to the synthesis of fine chemicals

Abstract A solid superbase whose basicity (H_) is higher than 37 has been prepared by the successive treatment of γ-alumina with alkali metal hydroxide and alkali metal at 200–600°C under nitrogen. The solid base has been found to be highly effective in the catalytic isomerization of olefinic double bonds and in the side-chain alkylation of alkylbenzenes with olefins.
