developed to provide both skeletal and stereochemical diversity. Each synthetic intermediate is also a desired polyketide fragment and no protecting group manipulations are required. A first-generation synthesis provides a 74-membered polyketide library comprising six different skeletal classes, each in one to five steps from propargylic alcohol precursors. A study of epoxyol opening reactions revealed
已经开发了一种有效的系统方法,用于聚酮化合物的多样性导向合成,以提供骨架和立体化学多样性。每种合成中间体也是所需的聚酮化合物片段,不需要保护基团的操作。第一代合成提供了一个由74个成员组成的聚酮化合物文库,该文库包含六种不同的骨架类,每类均距离炔丙醇前体一到五步。对环氧醇开启反应的研究表明,基于环氧化物构型的反应性趋势异常。
