Abstract
PURPOSE: A specific cyclohexylamine derivative is made to act on (±)-trans-chrysanthemum-monocarboxylic acid and optically resolved to make high-purity (+)- trans isomer used as a synthetic intermediate of an insecticide in high yield.
CONSTITUTION: (±)-trans-Chrysanthemum-monocarboxylic acid is made to react with an optically active cis-N-benzyl-2-(hydroxymethyl)cyclohexylamine in a solvent such as methanol to form a diastereomer salt. Then, it is optically resolved by utilizing the difference in solubility to collect (+)- or (-)-amine by treating with a base. Then, the product is treated with an acid to give (-) or (+)-trans-chrysanthemum-monocarboxylic acid.
