A stereoselective synthesis of the C9–C19 fragment of lyngbyaloside B and C highlighted, by an extension of our ether transfer methodology, enables the formation of tertiary ethers. 2-Naphthylmethyl ethers have been shown to proceed efficiently through ether transfer with high stereoselectivity and are easily deprotected by DDQ oxidation. Variation of the workup conditions results in the stereoselective
lyngbyaloside B 和 C 的 C9-C19 片段的立体选择性合成突出显示,通过我们的醚转移方法的扩展,能够形成叔醚。2-萘基甲基醚已被证明可以通过醚转移有效进行,具有高立体选择性,并且很容易通过 DDQ 氧化脱保护。后处理条件的变化导致合成-1,3-二醇单醚或二醚的立体选择性形成。
