The first synthesis of a newly discovered class of bacterial signaling molecules from Streptomyces coelicolor has been developed. These molecules, known as the methylenomycin furans (MMFs), trigger production of the antibiotic methylenomycin. The synthesis features a scandium triflate-catalyzed domino reaction of β-ketoesters and dihydroxyacetone yielding 2,3,4-substituted furans. The proposed reaction
已经开发了一种新发现的来自天蓝色链霉菌的细菌信号分子的合成方法。这些分子被称为甲基新霉素呋喃(MMF),触发了抗生素甲基新霉素的生产。该合成具有三氟甲磺酸scan催化的β-酮酸酯和二羟基丙酮的多米诺反应,生成2,3,4-取代的呋喃。所提出的反应顺序(醛醇缩合反应,环化和脱水芳构化)可能使人联想到生物合成反应,其中磷酸二羟丙酮酯和β-酮硫酯被酶缩合。
