The structure and absolute configuration of the marine antithrombotic product dysinosin A was confirmed by total synthesis. The strategy involved disconnections to three subunits, of which two were synthesized from the readily available l-glutamic acid, d-leucine, and d-mannitol. The Grubbs olefin metathesis carbocyclization reaction was utilized to prepare two intermediates.
通过全合成证实了海洋抗血栓形成产品肌胞苷A的结构和绝对构型。该策略涉及断开与三个亚基的连接,其中两个亚基由现成的 l-谷氨酸、d-亮氨酸和 d-甘露醇合成。Grubbs烯烃复分解碳环化反应用于制备两种中间体。
