The present invention relates to piperidine derivatives of formula (I) wherein Ar1, Ar2, RAr1, R1, R2, and R3 are as described in the description, their preparation, to pharmaceutically acceptable salts thereof, and to their use as pharmaceuticals, to pharmaceutical compositions containing one or more compounds of formula (I), and especially to their use as CXCR7 receptor modulators.
We have developed an effective approach to 1,2‐disubstituted diamondoids by palladium(II) acetate catalyzed functionalization of CH bond. Selective mono‐arylation of the adamantane framework was achieved using picolylamide as a directing group in yields up to 87 %. Kinetic studies in combination with deuterium labeling experiments, competitive experiments and mass spectrometry contribute to the mechanistic

through an imidoruthenium(V) intermediate, which is rapidly attacked by water to yield a Ru(II)-bound hydroxylamine radical, which is readily oxidized and deprotonated to produce the nitrosoruthenium(II) complex. The nitrosoruthenium(II) complex is quantitatively reduced to the original [Ru(bpy)2(mpea)]2+ complex at relatively negative potentials ( Epc = -0.2 V in 1.0 M H2SO4).
胺钌(II)络合物Ru(bpy)2(mpea)2+是通过1-甲基-1-吡啶-2-基乙胺(mpea)与Ru(bpy)2Cl2在乙醇/水中的直接反应制得的并分离为六氟磷酸盐。对该化合物的电化学分析表明,该化合物先后进行一电子氧化,生成酰胺基钌(III)中间体(E度'= 1.086 V vs NHE),然后再生成酰胺基钌(IV)(E度'= 0.928 V)或酰亚胺钌( IV)(E度= 1.083 V)络合物,具体取决于溶液的pH值(酰胺基钌(IV)物种的pKa = 2.62)。在更高的电势下(1.0 M H2SO4中的Epa = 1.5 V),酰胺或亚氨基钌(IV)不可逆地氧化为相应的亚硝基钌(II)络合物。根据b3lyp / cpcm / cep-31g(d)计算,出现了这种转换的机制,继续通过亚氨基钌(V)中间体进行处理,该中间体会受到水的快速攻击,从而生成与Ru(II)结合的羟胺自由基,该

We have developed a synthesis of 1,2‐substituted adamantane carboxylic acids and further bridged cycloalkanes (cage compounds) by palladium acetate‐catalyzed C−H bond oxidation. Acetoxylation of cycloalkane framework was performed using picolylamide as a directing group. Modification of the substrate, ligand design and variation of reaction conditions enabled us to study the mechanism of acetoxylation
