摘要：
TREATMENT OF A 13-ALKYLGONA-1,3,5(10),8-TETRAENE WITH ORGANIC PERACID RESULTS IN THE FORMATION OF A CORRESPONDING 8,9-EPOXY-13-ALKYLGONA-1,3,5(10)-TRIENE, WHICH UPON TREATMENT WITH ACID, IS RING-OPENED AND REARRANGED TO THE CORRESPONDING 13-ALKYLGONA-1,3,5(10),9(11)-TETRAEN-8-OL. CATALYTIC HYDROGENATION THEN AFFORDS THE CORRESPONDING 13-ALKYLGONA-1,3,5(10)-TRIEN-8-OL WHICH UPON DEHYDRATION GIVES THE CORRESPONDING 13-ALKYLGONA-1,3,5(10),7-TETRAENE. THERE IS THUS PROVIDED A ROUTE TO THE SYNTHESIS OF EQUILIN AND RELATED COMPOUNDS.
