A novel strategy for the stereoselective synthesis of substituted tetrahydropyrans has been developed on the basis of a domino olefin cross-metathesis/intramolecular oxa-conjugate cyclization catalyzed by the Hoveyda—Grubbs second-generation catalyst.

Domino rings: A general synthetic entry into labdane‐type diterpenoids has been developed based on an iridium‐catalyzed enantioselective polyenecyclization cascade. The potential of this process is demonstrated in the first total synthesis of the tetranorlabdane diterpene asperolide C (PMB=p‐methoxybenzyl, TMS= trimethylsilyl).
