Tetrahedron Letters, 9, p. 4885, 1968 DOI: 10.1016/S0040-4039(00)72784-5

General Description

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.
