A convergent total synthesis of the marine natural product dysiherbaine was accomplished. The key steps of the synthesis are an alkylation at the gamma-carbon of a protected glutamate with a highly substituted pyran derived from mannose, which was followed by a ring-contraction cascade reaction, which simultaneously gave the tetrasubstituted carbon and the hexahydrofuro[3,2-b]pyran ring system of the
完成了海洋天然产物dysiherbaine的聚合全合成。合成的关键步骤是在被保护的谷氨酸的γ-碳上用甘露糖衍生的高度取代的吡喃进行烷基化,然后进行环级联反应,同时生成四取代的碳和六氢呋喃[3,天然产物的2-b]吡喃环系统。
