Stereoselective synthesis of C1–C9 subunit of macrocyclic lactone—tylonolide is presented. Starting from 2-methylfuran and crotyl alcohol, a 2,5-disubstituted furan derivative was synthesized. Its oxidation leads to α,β-unsaturated dicarbonyl intermediate which has been transformed into acyclic fragment bearing five consecutive asymmetric centers.
提出了立体选择性合成大环内酯-泰诺醇的C1-C9亚基的方法。从2-甲基呋喃和巴豆醇开始,合成了2,5-二取代的呋喃衍生物。其氧化导致α,β-不饱和二羰基中间体转变为带有五个连续不对称中心的无环片段。
