Description and Uses
This simple piperidine derivative has been obtained from Girgensohnia diptera Bge. It is optically inactive and furnishes a crystalline picrate, m.p. 15 I-2°C and a picrolonate, m.p. 226°C.
Reactant for:
- sp3 C-H Bond activation with ruthenium(II) catalysts and C(3)-alkylation of cyclic amines
- One-pot synthesis of Z-cinnamic acids
Reactant for synthesis of:
- Unsymmetrical ureas
- Antibacterial imidazolium, pyrrolidinium, and piperidinium salts
- C1-C16 segment of goniodomin A via palladium-catalyzed organostannane thioester coupling
- Multi-targeted inhibitors of insulin-like growth factor-1 receptor and members of ErbB-family receptor kinases
