摘要
We report a regioselective entry to 3-bromo- and 4-bromo-5-hydroxy-5H-furan-2-ones by photooxidation of 3-bromofuran with a singlet oxygen in the presence of a suitable base. By this procedure, a variety of 3-substituted gamma-hydroxybutenolides have become for the first time easily accessible. Strategies employing these highly functionalized building blocks for the preparation of focused libraries of natural-like molecules are also discussed.
