An advanced intermediate for the synthesis of bengazole A (1) was prepared by direct grafting of oxazole to a protected side-chain synthon (prepared from d-galactose) through C-4-directed addition (oxazole numbering) to the ambident nucleophile, 2-lithiooxazole.
通过将恶唑直接接枝到受保护的亲核试剂上,通过C-4定向加成(恶唑编号),将恶唑直接接枝到受保护的侧链合成子(由d-半乳糖制备)上,从而制备了合成苯甲A(1)的高级中间体。-硫代恶唑。
