Synthesis of the novel natural product Phosphonothrixin has been accomplished in 6 steps and 24% overall yield from the commercially available Baylis-Hillman adduct derived from acetaldehyde and methyl vinyl ketone. The synthesis features use of a trisubstituted olefin as a latent a-hydroxyketone, which formally reverses the oxidation states of the hydroxyl and carbonyl functionalities. This alleviates
从乙醛和甲基乙烯基酮衍生的市售Baylis-Hillman加合物已通过6个步骤完成了新的天然产物膦丝菌素的合成,总收率为24%。该合成的特征在于使用三取代的烯烃作为潜在的α-羟基酮,其形式上逆转了羟基和羰基官能团的氧化态。这减轻了在通过亚稳中间体进行的替代合成中遇到的一些困难。
