see text]. Stereocontrolled construction of the 12-membered diene and triene lactones 1, 2, and 3, characteristic of the antitumor agent oximidines I and II, are reported and were based on an intramolecular Castro-Stephens coupling for the construction of a cyclic enyne or dienyne followed by stereoselective reduction of the cyclic alkyne for introduction of the cis-olefin of the targets. A comparison
