顺-1,5-二甲基二环[3.3.0]辛烷-3,7-二酮

顺-1,5-二甲基二环[3.3.0]辛烷-3,7-二酮用途

Olefination of cis-1,5-dimethylbicyclo[3.3.0]octane-3,7-dione with (carbethoxyethylidene)triphenylphospharane under controlled microwave heating has been investigated. It reacts with carbon disulfide, strong base and an alkylating agent in dipolar aprotic solvents to yield racemic mixtures of 2-dialkylthio-methylene compounds.
