摘要：

Tonghaosu, 2-[(Z)-hexa-2,4-diynylidene]-1,6-dioxaspiro[ 4,4] non-3-ene (1a), and its spiroketal enol ether analogues (1b-d and 2) were efficiently converted into interesting cyclopentenone derived oxabicyclic compounds. By applying this reaction protocol the natural product chrycorin was easily synthesized in its racemic form. A reaction mechanism for this is proposed.
