A stereoselective synthesis of (-)-tetrahydrolipstatin is described. The synthesis involves an asymmetric ester derived titanium enolate anti-aldol reaction, a nitro-aldol reaction to append the C-2' C(11) side chain, and a diastereoselective reduction of a beta-hydroxy ketone to an anti-1,3-diol functionality followed by its elaboration to (-)-tetrahydrolipstatin.
描述了(-)-四氢脂抑素的立体选择性合成。该合成涉及不对称酯衍生的烯醇钛反式羟醛缩合反应、用于连接C-2'C(11)侧链的硝基羟醛缩合反应,以及将β-羟基酮非对映选择性还原为反式-1,3-二醇官能团,随后将其转化为(-)-四氢脂抑素。
