The antifungal agent (+)-restricticin (1) was prepared in 12 steps from ketone (S)-8. The key steps are (i) the boron-mediated anti aldolreaction of (S)-8 with 9 to give 13 and (ii) the cyclisation reaction 4 → 15.

lipid I and II analogs is reported. The modular route was based on a three coupling strategy involving an efficient solid phase synthesis of the elaborate peptide fragment, which proceeded with excellent yield and stereoselectivity and was efficiently applied for the convergent synthesis of 3-lipid I and II. Furthermore, the generality of this route was demonstrated by synthesis of 3-lipid I congeners
报告了有关开发法呢基脂质 I 和 II 类似物的新型合成序列的设计、策略和策略的全部细节。模块化路线基于三偶联策略,涉及精细肽片段的有效固相合成,其以优异的产率和立体选择性进行,并有效地应用于 3-脂质 I 和 II 的聚合合成。此外,该途径的普遍性通过合成金黄色葡萄球菌和粪肠球菌特有的 3-脂质 I 同系物得到证实。所有 3-脂质 I 和 II 结构单元均以高纯度获得,显示出高光谱分辨率。
