Dry air is the source of molecular nitrogen for reactions with TiL , Li, and TMSCl (L = Cl, OiPr; TMS = trimethylsilyl). The nitrogen-titanium complexes thus prepared can be used to synthesize indoles, pyrroles, and lactams from carbonyl compounds. Applying this method to 1 provides access to 2, the key compound in the synthesis of (±)-lycopodine.
干燥空气是与TiL、Li和TMSCl(L = Cl、OiPr;TMS = 三甲基硅基)发生反应的分子氮源。由此制备的氮 - 钛配合物可用于从羰基化合物合成吲哚、吡咯和内酰胺。将该方法应用于1可得到2,即(±)-石松碱合成中的关键化合物。
