from commercially available (+)-sclareolide, the first synthesis of zerumin B was achieved by a concise, highly efficient pathway featuring stereoselective addition of a new silyloxyfuryltitanium reagent to an aldehyde intermediate and silyloxyfuran oxyfunctionalization as key steps. The synthesis established the relative and absolute configuration of zerumin B along with its identity with a purportedly
从市售(+)-香紫苏内酯开始,通过一种简明高效的途径实现了蛇毒蛋白B的首次合成,该途径的特征是将新的甲硅烷氧基呋喃基钛试剂立体选择性地添加到醛中间体中,并将甲硅烷氧基呋喃的氧基官能化作为关键步骤。合成建立了相对的和绝对的zerumin B的构形,并与从植物肾小球鼠分离的据说是新的二萜一起鉴定了它的身份。
