The Uses of Tropine
Tropine as an oxidative product of Tropane, used to synthesize alkaloid derivatives. Benzatropine and etybenzatropine are derivatives of tropine. It is also a building block of atropine, an anticholinergic drug prototypical of the muscarinic antagonist class.
Definition
ChEBI: A derivative of tropane having a hydroxy group at the 3-position.
Purification Methods
Distil 3-tropanol in steam and crystallise it from Et2O or toluene/pet ether. It sublimes at 60o/0.1mm. Hygroscopic. The hydrochloride has m 280o (from EtOH/Et2O). [Beilstein 21 H 16, 21 I 197, 21 II 17, 21 III/IV 168, 21/1 V 219.]
