日期:——
The asymmetric total synthesis of the anti-proliferative macrolide (+)-neopeltolide has been completed. The stereochemically defined trisubstituted tetrahydropyran ring was constructed via a catalytic hetero-Diels–Alder reaction creating two new chiral centers in a highly diastereoselective manner. The other key features of this synthesis included Brown's asymmetric allylation to install the requisite

An 11-step synthesis of (+)-neopeltolide was developed. The C1–C7 carboxylic acid and the C8–C16 alcohol were prepared, each in six steps, from (R)- and (S)-epichlorohydrin, respectively. After esterification, our tandem macrocyclization/transannular pyran cyclization strategy was applied to a stereocontrolled construction of the neopeltolide macrolactone. The side chain was synthesized in six steps
开发了 (+)-neopeltolide 的 11 步合成。C1-C7 羧酸和 C8-C16 醇分别由 ( R )- 和 ( S )- 表氯醇分六步制备。酯化后,我们的串联大环化/跨环吡喃环化策略应用于立体控制的新环内酯大环内酯结构。侧链由 4-恶唑甲酸乙酯通过钯催化的交叉偶联分六步合成。Neopeltolide大环内酯与侧链的Mitsunobu反应完成了合成。
