An X-ray structure analysis hasĪllowed us to determine unambiguously its stereochemistry and deduce theĪbsolute configuration of its oily precursor γ-Epoxyhimachalene 1. The structure of the newly prepared 2 (scheme 2) has been establishedįrom its 1H and 13C NMR spectral data. Transform it into a solid derivative by cycloaddition reaction of aĭihalocarbene on the remaining cyclohexenic double bond. Sesquiterpene γ-himachalene without crystallographic evidence of itsĪbsolute configuration as the product was oily. Synthetise γ-Epoxyhimachalene 1 (scheme 1) from naturally occurred In the aim of preparing new epoxides from natural products, we recently Widespread occurrence, biological and synthetic utilities, the synthesis of Besides, many natural products possess thisĪs an essential structural moiety for their biological activities (Yang, ![]() Thus, epoxidesĪre important precursors in the synthesis of Antifungal products (Taylor etĪl., 1991) and different pheromones (Mori, 1989,Īl., 1997). Epoxides are valuable intermediates frequently used as versatile buildingīlocks in organic synthesis (Qu et al., 2009).
