The synthesis of a phosphadecalone system

Y. Kashman, H. Ronen

Research output: Contribution to journalArticlepeer-review


The 2-phosphabicyclo[4.4.0]decan-5-onic system (2) was synthesized by a double Michael addition of phenylphosphine to propenylcyclohexenyl ketone (1). This dienone (1) can be prepared starting from either cyclohexanone by a known method, or from cyclohexene by its acylation with crotonic anhydride in the presence of SnCl4. The NMR of the phosphine and several of its derivatives in comparison with the aza analog, as well as the Mass spectra fragmentation pattern, are discussed,.
