[structures: see text] A versatile (S)-3-(hydroxymethyl)butane-1,2,4-triol building block has been synthesized starting from D-isoascorbic acid, a common food preservative. The key transformation in this approach was the introduction of branching through a high yield and fully regioselective epoxide opening. This flexible synthon has been elaborated to a new class of (dihydro-)N-homo(phyto)ceramides
[结构:见正文]从D-异抗坏血酸(一种常见的食品防腐剂)开始合成了一种多用途的(S)-3-(羟甲基)丁烷-1,2,4-三醇结构单元。这种方法的关键转变是通过高收率和完全区域选择性的环氧开放来引入支链。这种灵活的合成子已被精细化为一类新型的(二氢-)N-高(植物)神经酰胺。
