Phenylacetic acid derivs. of forumla (I) and their salts are new. In (I) A = 2-E-3-G-4-L-5-M-pyrrol-1-yl; 3-G-4-L-5-M-pyrazol-1-yl; 2-M-4-G-5-E-imidazoly-1-yl; 4-L-5-M-1H-1,2,3-triazol-1-yl etc.; E, G, L and M = 3-8C cycloalkyl, H, tetrazolyl, halo, 1-6C perfluoroalkyl, OR4, COR5, etc. R4 = H; 1-8C alkyl or acyl, phenyl (opt. substd.) or OH-protecting gp.; R5 = H, OH, up to 8C alkyl or alkoxy, NR9R10 or NR9.SO2R11; R9 and R10 = H, up to 8C alkyl or acyl, or phenyl (opt. substd.) R11 = 1-8C alkyl, benzyl, 2-phenylvinyl or phenyl (opt. substd.) R6 = H, OH, MeCOO, 1-8C alkyl or phenyl. B = up to 4C linear alkyl, alkenyl or alkynyl; D = H, halo, NO2, OH, CF3, CF3O, up to 6C alkyl, alkoxy or alkoxycarbonyl, CN, COOH, or NR9R10; R1 and R2 = H; OH, 1-10C alkyl (opt. substd. by halo, 3-8C cycloalkyl or phenyl (itself opt. substd. by halo, NO2, OH or 1-8C alkyl or alkoxy)), 3-12C cycloalkyl or cycloalkenyl; or phenyl (opt. substd. by halo or 1-6C alkyl or alkoxy); or R1 and R2 together complete a 3-7 membered satd. or unsatd. carbocycle (opt. substd. by 1 or 2 of 1-6C alkyl or alkoxy, phenyl, OH or halo); R3 = tetrazolyl, CN; COR18, CONR19R20 etc. R18 = OH, 1-10C alkoxy or phenoxy; R19 and R20 are as R9 and R10; R20 may also be -CHR25-CHR26-OR27; R25 and R26 = H, phenyl, benzyl or 5-7 membered, satd. or unsatd. heterocycle with up to 3 N, S or O atoms, etc. R27 = H or 1-8C alkyl. - |
