4-tetrakis(diphenylphosphinomethyl)cyclopentane as a catalyst, a range of aryl bromides undergoes Heck reaction with acrolein ethylene acetal. With this acetal, the selective formation of 3-arylpropionic acids/esters was observed. The functional group tolerance on the aryl halide is remarkable; substituents such as fluoro, methyl, methoxy, acetyl, formyl, benzoyl, nitro or nitrile are tolerated. Furthermore

, A, B, X, W and n are as defined in the description, and pharmaceutically acceptable salts of such compounds. These compounds are useful as calcium channel blockers.
The invention relates to compounds of formula (I), wherein R1, R2, R1a, R2a, R3, R4, A, B, X, W and n are as defined in the description, and pharmaceutically acceptable salts of such compounds. These compounds are useful as calcium channel blockers.
Novel compounds of the structural formula I, and the pharmaceutically acceptable salts thereof, are inhibitors of TarO and may be useful in the prevention, treatment and suppression of diseases mediated by TarO, such as bacterial infections, including gram negative bacterial infections and gram positive bacterial infections such as MRSA and MRSE, alone or in combination with a β-lactam antibiotic.
结构式 I 的新型化合物及其药学上可接受的盐类是 TarO 的抑制剂,可用于预防、治疗和抑制由 TarO 介导的疾病,如细菌感染,包括革兰氏阴性细菌感染和革兰氏阳性细菌感染,如 MRSA 和 MRSE,可单独使用或与β-内酰胺类抗生素联合使用。
