A highly efficient [1,2]-Brook rearrangement of silyl glyoxylates has been developed using DBU as the organobase-catalyst. This [1,2]-Brook rearrangement is applicable to a number of thiols and secondary phosphine oxides containing acidic protons. These nucleophiles afford the corresponding Brook products in high yields. Using this methodology, a formal synthesis of anti-HIV drug compound lamivudine was realized.
以DBU作为有机碱催化剂，开发了一种高效的甲硅烷基乙醛酸酯的[1,2]-布鲁克重排反应。这种[1,2]-布鲁克重排反应适用于许多含有酸性质子的硫醇和二级氧化膦。这些亲核试剂能高产率地得到相应的布鲁克产物。利用该方法，实现了抗HIV药物化合物拉米夫定的形式合成。
