Comprehensive Summary

The stereochemical synthesis of highly substituted Danishefsky-type dienes remains unsolved in organic chemistry. We describe a simple and efficient approach for the stereoselective synthesis of Danishefsky-type trisubstituted dienes from readily available propargylic esters via Pd-catalyzed dienylation reaction through the key intermediate metallacyclobutene in a regio-, chemo- and stereoselective fashion. This method facilitates a broad range of challenging trisubstituted dienes with a high level of stereocontrol. The synthetic utilities of oxygenated trisubstituted dienes have been demonstrated by the downstream chemistry, which notably undergoes Diels-Alder reaction with a variety of electron-deficient dienophiles to furnish multisubstituted cyclohexenes in good yields with excellent stereoselectivity.
