- 中文摘要: Deprotonation of the title compound followed by treatment with 5-iodo-1-pentene or 6-iodo-1-hexene gave the alkylated products which upon refluxing in toluene yielded the dienes 8a and 8b. Intramolecular Diels-Alder reactions were achieved by heating the dienes 8a and 8b in toluene in a sealed tube at 160-180.degree.C to give bicyclo.(4.3.0.)nonene and bicyclo.lbrak.4.4.0.rbrak.decene, respectively, in good yield. The stereochemistry of the cyclization products was determined, and was rationalized by comparison of the possible transition states involved.
