Cross coupling of 3-bromopyridine and sulfonamides (R1NHSO2R2·R1 = H, Me, alkyl; R2 = alkyl and aryl) catalyzed by CuI/1,3-di(pyridin-2-yl)propane-1,3-dione

N-(3-Pyridinyl)-substituted secondary and tertiary sulfonamides have been synthesized in good to excellent yields by the reaction of 3-bromopyridine with primary and secondary alkyl and aryl sulfonamides (MeSO2NH2, MeSO2NHMe, TolSO2NH2, TolSO2NHMe, 1,3-propanesultam, and 1,4-butanesultam), catalyzed by CuI (20 mol %) and 1,3-di(pyridin-2-yl)propane-1,3-dione (20 mol %) with K2CO3 (200 mol %) in DMF (0.17 M for ArBr) at 110-120 °C over 36-40 h. 2-Bromopyridine, 4-bromopyridine, and a wide variety of substituted phenyl bromides can also be successfully coupled with sulfonamides under these reaction conditions.

In the search of Factor Xa (FXa) inhibitors structurally different from the pyrazole-based series, we identified a viable series of enantiopure cis-(1R,2S)-cycloalkyldiamine derivatives as potent and selective inhibitors of FXa. Among them, cyclohexyldiam
Synthesis of N-arylated sultams: Palladium- and copper-catalyzed cross coupling of aryl halides with 1,4-butane and 1,3-propanesultams

Palladium-catalyzed cross coupling of 1,4-butanesultam and 1,3-propanesultam with a variety of aryl halides was found to provide the desired products in 62-93% isolated yield using Xantphos as ligand. The Pd-catalyzed reaction was found to be superior to the analogous Cu-catalyzed reaction based on product yields, reaction rates, and substrate scope.

Page/Page column 114, (2010/02/08)
The present application describes lactam-containing cyclic diamines and derivatives thereof of Formula I: or pharmaceutically acceptable salt forms thereof, wherein M is a non-aromatic carbocycle or heterocycle. Compounds of the present invention are useful as inhibitors of trysin-like serine proteases, specifically factor Xa.
