The coupling of organozinc compounds with homochiral 2-(3-iodophenyl)propanoic and 2-(4-iodophenyl)propanoic acids in the presence of palladium is a general method for the synthesis of opticallyactive arylpropanoic acids.
Nonsteroidal antiinflammatroy agents. 2. Synthesis of 4',5-disubstituted 3-diphenylylacetic acids and their derivatives with antiinflammatory and analgesic activities
3-biphenylylacetic acids (5a-n) and several alpha-methyl derivatives (5o-v) were prepared as analogues of a newly developed nonsteroidal antiinflammatory agent, 5'-chloro-5-methoxy-3-biphenylylacetic acid [1 (DKA-9), R = 4-C1Ph; R' = Me], and evaluated for antiinflammatory and analgesic activities using both carrageenan rat paw edema and AcOH writhing assays. Among them, 5-fluoro-3-biphenylylacetic acid (5m) showed
