A three-step convergent synthesis of an immunostimulatory oxylipin was developed using an olefin cross metathesis approach. The alkene fragments were prepared in two steps from commercially available starting materials with high stereoselectivity. In particular, an organocatalytic aldehyde α-oxygenation gave high enantioselectivity and yield using as little as 2 mol% catalyst. This synthesis represents
使用烯烃交叉复分解方法开发了免疫刺激性磷脂的三步收敛合成法。用高立体选择性从市售起始原料分两步制备烯烃片段。特别地,使用少至2mol%的催化剂,有机催化的醛α-氧化给出了高的对映选择性和收率。该合成代表了任何含有3-ene-1,2,5-三醇部分的天然产物的最短合成,并以33%的总收率递送了免疫刺激性的脂蛋白。
