Potassium-competitiveacidblockers (P-CABs) constitute a new therapeutic option for the treatment of acid-related diseases that are widespread and constitute a significant economical burden. Enantiomerically pure tetrahydrochromenoimidazoles were prepared using the readily available candidate 4 (BYK 405879) as starting material or the Noyori asymmetric reduction of ketones as key reaction. A comprehensive
钾竞争性酸阻滞剂(P-CAB)构成了治疗与酸有关的疾病的新的治疗选择,这些疾病与疾病相关的疾病广泛且构成重大的经济负担。使用容易获得的候选物4制备对映体纯的四氢色氮咪唑(BYK 405879)作为起始原料或Noyori酮的不对称还原是关键反应。建立了关于5-羧酰胺和8-芳基残基对体外活性,Ghosh Schild大鼠体内酸抑制和对hERG通道的亲和力影响的综合SAR。此外,通过瘘管犬的24 h pH测量,检查了最有希望的目标化合物的抗分泌作用的功效和持续时间,与Ghosh Schild大鼠相比,观察到了明显不同的SAR。鉴定了几种与候选物4具有可比性的四氢色氮咪唑。

potassium-competitive acid blockers (P-CABs). The title compounds were prepared following synthetic pathways that relied either on a Claisen rearrangement/cross-metathesis reaction or on the (asymmetric) reduction of prochiral ketones. The influence of the character of the substituents R3, R6, and Ar on the biological activity and the physicochemical properties of the target compounds was examined. In contrast

Chiral spiro N,N‐diarylphosphoramidites were synthesized. These new chiral spiro monophosphoramidites were efficient ligands for iridium‐catalyzedasymmetrichydrogenation of unfunctionalized enamines derived from simple alkyl aryl ketones, providing chiral tertiary amines in good enantioselectivities (up to 90% ee).
