A simple and highly efficient stereoselective total synthesis of dodoneine (1), a naturally occurring bioactive 5,6‐dihydro‐2H‐pyran‐2‐one, was achieved. The synthesis involved Keck's asymmetric allylation, iodine‐induced electrophilic cyclization, and Grubbs' catalyzed ring‐closing metathesis as key steps.
实现了一个简单而高效的立体选择多多宁(1)的全合成,它是一种天然存在的生物活性5,6-二氢-2 H-吡喃-2-酮。合成涉及Keck的不对称烯丙基化,碘诱导的亲电环化和Grubbs催化的闭环复分解反应等关键步骤。
