NICOTINAMIDE DERIVATIVES USEFUL AS PDE4 INHIBITORS
-
Page/Page column 85-86, (2010/02/10)
This invention relates to nicotinamide derivatives of formula (I) and to pharmaceutical compositions containing, and the uses of such derivatives as PDE4 inhibitors wherein R7 is attached to the 3-or 4-position of the phenyl ring and is S(O)pR8, R8 is (C1-C4)alkyl optionally substituted by (C3-C6)cycloalkyl; m is 0 or 1; L is a (C3-C8)carbocyclic non-aromatic ring; and the remaining variables are as defined in the claims.

Acylative kinetic resolution of racemic cyclic cis-amino alcohol derivatives with a chiral nucleophilic catalyst proceeds enantioselectively (s = 10-21) at ambient temperature to give enantiopure recovered materials, and the % conversion of the acylation can be readily controlled by the amount of acid anhydride.

(±)-cis-N-Benzyloxycarbonyl-2-aminocyclopentanol was efficiently resolved by O-acylation with Pseudomonas cepacia lipase, as was (±)-cis-N- benzyloxycarbonyl-2-aminocyclohexanol when Candida antarctica lipase was used.
