Provided are a novel triphenyl phosphine derivative synthesized from a triphenylphosphine and a hydroxy-containing lactone; a palladium and a nickel complexes comprising the derivative as a ligand; and a process for preparing a biaryl derivative using the complex as a catalyst. A product can be easily separated from a catalyst or a phosphorus compound, and biaryl derivative can be synthesized in a higher yield, by using the complex of the present invention as a catalyst.
N-Alkyl-N'-cyano-N"-(substituted phenyl-pyridinylmethyl) guanidine derivatives were synthesized and tested for inhibitory activity against gastric secretion in rats. Several of the compounds synthesized showed an inhibiting activity as potent as that of cimetidine against basal gastric secretion but showed less potent activity than cimetidine against histamine-stimulated gastric secretion. Some structure-activity relationships are discussed.
