| contents | Enantioselective Total Synthesis of Breviones Utilizing a Bio-Inspired Skeletal Editing Strategy. Liu, Yaqian Zhou, Yuanjun Xu, Yaoyao Liu, Shuangning Huang, Qingyang Jia, Hongli Li, Houhua Stereoisomerism Diterpenes Pyrones Molecular Structure Inspired by skeletal editing transformations in the biosynthesis of spiro diterpene pyrones, we herein present an enantioselective total synthesis of the meroditerpenoids breviones B, C, and N. Our synthetic strategy features a series of bio-inspired skeletal editing transformations, including a Dowd-Beckwith ring expansion to construct the seven-membered A-ring, and an annulative skeletal rearrangement that couples terpene and α-pyrone motifs into the spiro diterpene pyrone framework. This latter transformation involves a novel dihydropyran-to-dihydrofuran ring contraction, a strategy that has proven applicable to a diverse range of terpene and pyrone fragments. In addition, during the synthesis, we also developed a SnCl-mediated intramolecular hydroalkylation of alkenyl β-keto esters, which enables the concurrent assembly of the fused B/C ring system along with three contiguous stereocenters. |
