According to a general concept for the total synthesis of pseurotin A (1), a secondary metabolite of Pseudeurotium ovalis STOLK, 5-[(1S,2S,Z)-1,2-dihydroxyhex-3-enyl]-2,2,4-trimethylfuran-3(2H)-one (17) was prepared. It is a model substance for the substituted furan-3(2H)-one moiety of 1. The aldol condensation of the aldehyde 26, derived from D-glucose, and the enolate of ketone 29 served as key reaction
根据全合成假单胞菌素A(1)的一般概念,椭圆假单胞菌STOLK的次生代谢物5-[(1 S,2 S,Z)-1,2-二羟基己基-3-烯基] -2,制备2,4-三甲基呋喃-3(2H)-一(17)。它是为取代的呋喃-3(2模型物质ħ) -酮的部分1。衍生自D-葡萄糖的醛26的醛醇缩合和酮29的烯醇化物是关键反应。
