SYNTHESIS OF NOVEL COMPOUNDS USEFUL FOR PRODUCTION OF JUVABIONE

Webb9 juni 1998 · Juvabione [the methyl ester of todomatuic acid (Fig. 1 )] is a component of “paper factor,” a mixture of oxygenated bisabolane sesquiterpenes that is responsible for the failure of certain insects to molt into adults when reared in contact with paper made from fir species (genus Abies) ( 22 – 25 ). WebbUse of 15-crown-5 in conjunction with sodium hydride afforded a 1.27-fold rate enhancement over the course of a bicyclic diene alkoxide's sigmatropic conversion to enolate product, while the same reaction with HMPT in 15-crown-5's place did not appreciably affect the rate. lebron james baggy shorts
