[求助] 帮忙翻译一篇有机化学文献的题目跟摘要 要准确点 谢谢

题目 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.
