題目 A Short Total Synthesis of (±)-Epimeloscine and (±)-Meloscine Enabled by a Cascade Radical Annulation of a Divinylcyclopropane 摘要 ABSTRACT: The first stereoselective synthesis of epime- loscine has been accomplished in 13 total steps with a longest linear sequence of 10 steps. The core of the synthesis takes only five steps, the key ones being acylation, stereoselective tandem radical cyclization of a divinylcyclopropane to make two rings, and group-selective ring-closing metathesis of the resulting divinylcyclopentane to make the last ring.

題目 A Short Total Synthesis of (±)-Epimeloscine and (±)-Meloscine Enabled by a Cascade Radical Annulation of a Divinylcyclopropane一種簡短的通過Divinylcyclopropane串聯(lián)自由基環(huán)化實現(xiàn)的(±)-Epimeloscine 和 (±)-Meloscine全合成方法 摘要 ABSTRACT: The first stereoselective synthesis of epimeloscine has been accomplished in 13 total steps with a longest linear sequence of 10 steps.首先,epimeloscine的立體選擇性合成通過總計13步包括一個最長的線性次序10步反應(yīng)實現(xiàn)。 The core of the synthesis takes only five steps, the key ones being acylation, stereoselective tandem radical cyclization of a divinylcyclopropane to make two rings, and group-selective ring-closing metathesis of the resulting divinylcyclopentane to make the last ring.合成的核心反應(yīng)只需要5步,關(guān)鍵步驟包括;ivinylcyclopropane的立體選擇性串聯(lián)自由基環(huán)化形成兩個環(huán)和所得divinylcyclopentane的官能團選擇性合環(huán)歧化形成最后的環(huán)。 化合物名稱樓主應(yīng)該比別人清楚,我查似無必要,請樓主替換 |
