Highly stereoselective total syntheses of polyrhacitide A and epi-cryptocaryolone have been achieved in 11 steps with high overall yield of 24% and 28%, respectively, following a recently developed strategy for the construction of trans-2,6-disubstituted-3,4-dihydropyrans. In this report, the versatility of iodo-cyclization for the total syntheses of polyrhacitide A and epi-cryptocaryolone is demonstrated
遵循最近开发的反式-2,6-二取代-3,4的构建策略,已通过11个步骤实现了多杀菌素A和表隐隐烯醇酮的高度立体选择性总合成,分别具有24%和28%的高总收率。-二氢吡喃。在该报告中,证明了碘化环化反应对多杀菌素A和Epi- cryptocaryolone进行总合成的多功能性。
