The enantioselective synthesis of the eunicellin ophirin B has been completed. A ring-closing metathesis provides efficient access to the oxonene ring, and a highly diastereoselective intramolecular Diels-Alder reaction results in the formation of the hydrobenzofuran portion of the molecule.
eucellin ophirin B的对映选择性合成已经完成。闭环复分解提供了有效进入氧酮环的途径,高度非对映选择性的分子内 Diels-Alder 反应导致分子的氢苯并呋喃部分的形成。
