  Synthesis of Analogues of (−)-Cytisine for in Vivo Studies of Nicotinic Receptors Using Positron Emission Tomography

  摘要：

  9-Substituted analogues of (-)-cytisine were synthesized in high yields via palladium-mediated couplings of either 9- (-)-bromocytisine and organostannanes or 9-(-) trimethylstannylcytisine and fluorobromobenzene. The protection of the amine with a nitroso group and the use of PdCl2(PPh3)(2) to carry out the Stille reaction allowed the rapid synthesis of 9-(4'-[F-18]fluorophenyl)cytisine (F-18: t(1/2) = 109.7 min), a new promising radioligand (radiochemical yield: 10% from [F-18]KF, 150 min, four steps) for positron emission tomography studies of alpha(4)beta(2) nicotinic receptors.
