Total synthesis of (+)-epoxydictymene. Application of alkoxy-directed cyclization to diterpenoid construction

An enantioselective synthesis of (+)-epoxydictymene (1) is reported. Condensation of the enantiopure aldehydo ester 5 with (S)-3-isopropylcyclopentenyllithium proceeds selectively to afford 13. Once this lactone was methylenated with the Tebbe reagent, th
