Unexpected Diels–Alder/Carbonyl-ene Cascade toward the Biomimetic Synthesis of Chloropupukeananin
摘要:
The biomimetic synthesis of the advanced model compound of chloropupukeananin has been achieved. The present synthesis features an unexpected enantiomer-differentiating Diels-Alder/carbonyl-ene cascade under high-pressure conditions and a base-promoted migration of the salicyl group.

The total synthesis of pestheic acid based on an intramolecular SNAr reaction without a nitro group and the asymmetricsynthesis of (−)-maldoxin by a catalytic enantioselective oxidative dearomatization of pestheic acid are described. The reactivity of (−)-maldoxin as a diene in the Diels–Alder reaction is also investigated.
描述了基于不具有硝基的分子内S N Ar反应的整个鼠疫酸合成以及通过对戊酸的催化对映选择性氧化脱芳香化反应(-)-maldoxin的不对称合成。还研究了在Diels-Alder反应中(-)-maldoxin作为二烯的反应性。
