  6-(1-ethynyl-1-cyclopentan-1-oxy)-2,3-dihydro-6H-pyran-3-one 在 copper(l) iodide 、 zinc chloride diethyl ether 、 三苯基膦 、 palladium dichloride 作用下， 以 1,2-二氯乙烷 为溶剂， 生成 (1RS,8SR,12SR)-6-methylene-3-spirocyclopentan-2,11-dioxatricyclo<6.3.1.0^4,12>dodec-4-en-9-one

  摘要：

  4-Methylpent-4-en-2-yn-1-ols and 6-hydroxy-2,3-dihydro-6H pyran 3-ones are condensed in different ways to a series of tricyclic dioxadienones which contain the basic framework of the cadlinolides. A mechanism of the intramolecular enyne-ene cycloisomerization and the origin of the resulting type I and type II dienes is proposed.
