The asymmetric synthesis of 8,4′-oxyneolignans (−)-virolin, (−)-surinamensin and a number of analogues has been achieved. A divergent synthesis was used, with all compounds being elaborated from a single chiral aldehyde derived from ethyl lactate. In the 15 compounds that were tested, the level of substitution on the A-ring was found to directly influence the activity against Leishmania donovani whilst
已经实现了8,4'-氧新木聚糖(-)-virolin,(-)-surinamensin和许多类似物的不对称合成。使用了发散性合成,所有化合物均由衍生自乳酸乙酯的单一手性醛精制而成。在测试的15种化合物中,发现A环上的取代水平直接影响针对多形利什曼原虫的活性,而针对恶性疟原虫的活性受众多取代和立体化学因素的影响。
