An enantioselective total synthesis of untenone A and plakevulin A has been achieved. Construction of a cyclopentene derivative, the key intermediate in this synthesis, was carried out by using a ruthenium-catalyzed ring-closing metathesis reaction of a divinyl compound, prepared from octadecanal in several steps including the Sharpless asymmetric epoxidation to generate a chiral quaternary carbon
已经实现了 untenone A 和 plakevulin A 的对映选择性全合成。该合成中的关键中间体环戊烯衍生物的构建是通过使用钌催化的二乙烯基化合物的闭环复分解反应进行的,该化合物由十八烷醛在几个步骤中制备,包括 Sharpless 不对称环氧化以生成手性季碳中心.
