The enantiospecific total synthesis of the cytotoxic guaipyridine sesquiterpene alkaloid (+)-cananodine (1) is described. A chiral pool/chiral auxiliary basedapproach is described for the synthesis of a key oxazolidinone intermediate. Subsequent key steps involve diastereoselective oxazolidinone allylation, cycloheptenylmethanol formation using ring-closing olefin metathesis, microwave-assisted decarboxylative
