Efficient Solution-Phase Parallel Synthesis of 4-Substituted N-Protected Piperidines

Practical conditions for the synthesis of 4-substituted N-protected piperidines through CuCN·2LiBr-catalyzed organozinc additions to 1-acylpyridinium salts and subsequent hydrogen-transfer hydrogenation have been established. The reaction sequence is performed at room temperature and provides 4-substituted N-protected piperidines in excellent overall yields without the isolation of intermediate dihydropyridines, In those cases in which the organozinc addition results in mixtures of 2- and 4-substituted dihydropyridines, the 2-substituted isomers are efficiently scavenged with maleic anhydride and subsequently removed by a mild extractive workup with NaHCO3 (sat.). The N-acyl group can conveniently be exchanged from N-phenoxycarbonyl to N-tBoc, thus allowing orthogonal deprotection strategies. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003.

Compounds and methods are provided for the treatment of disease conditions in which modification of cholinergic, especially muscarinic m1, m4, or both m1 and m4, receptor activity has a beneficial effect. In the method, an effective amount of a compound is administered to a patient in need of such treatment.
(Benzoylphenyl)piperidines: A new class of immunomodulators

, p. 1545 - 1552 (2007/10/02)
A series of (benzoylphenyl)piperidines has been synthesized and evaluated for activity as immunomodulators. Several of these compounds show good activity in primary screening on the basis of the lymphocytes mitogenic response to Con A, PHA, and PWM. A chloro group in position 4 of the benzoyl moiety as well as an amino group (or a carbamate derivative) para to the piperidine nucleus seems to be essential for activity. The depicted compounds may be considered as the first examples of a new series of immunomodulators.
