Abstract: 6-Sulfony-13-oxybicyclo[9.3.0]tetradec-3,8-diyne is the precursor of the bicyclic enediyne which has been synthesized from cis-1,2,3,6-tetrahydropathalican hydride by 8-step reactions. We got the goal compound by reduction of anhydride, ozonolysis of 8-oxabicyclo[4.3.0]non-3-ene, Witting reaction with PPh3/CBr4, formation of alkyne and esterification, reduction of the ester, formation of the mesylate, cyclization with sodium sulfide nonhydrate. The structures of new compounds 4_9 have been identified by elementary analysis, NMR, IRand MS spectra.

Key words: Heterocyclic compound, Cyclo-1,5-diyne-3-ene, Anticancer antibiotics
