Novel tertiary phosphine oxides are described which act as masked secondary phosphine oxides. The protection of the reactive P-H bond allows generation of a carbanion alpha to phosphorus and subsequent alkylation with an oxetane. The free P-H can then be liberated with anhydrous acid. This functionality can then be further alkylated to generate novel tertiary phosphine oxide backbone modified DNA.
新型叔腾氧化物被描述为隐匿的仲腾氧化物。对活性P-H键的保护使得能够在磷的α位生成碳负离子,随后与氧杂环丁烷进行烷基化。然后可以通过无水酸释放自由的P-H。这一功能性可以进一步烷基化,以生成修饰了新型叔腾氧化物骨架的DNA。
