Abstract
The cis-bicyclo[3.3.0]octane-3,7-dione 1a and its 1,5-dimethyl derivat ive 1b react with carbon disulfide, strong base and an alkylating agen t in dipolar aprotic solvents giving racemic mixtures of 2-dialkylthio methylene compounds 2, whereas in the presence of two equivalents of c arbon disulfide and the appropriate amount of basel and further alkyla ting agent the cis-2,6-bis(dimethylthio-methylene) derivatives 3 are f ormed. The crystal and molecular structure of 3a has been investigated by X-ray analysis.
