    A rhodium(I)‐catalyzed direct CH bond olefination of pyridyl‐substituted arenes with readily available vinyl carboxylic acids has been realized. This reaction occurred efficiently without the need for any external oxidant, affording the ortho‐olefinated products in high yields and excellent regioselectivities. Diversely substituted vinyl carboxylic acids behaved as efficient olefination reagents under

    Amino- or guanidino-phenylpropionic ester derivatives represented by the formula: ##STR1## wherein R is --NH.sub.2 or ##STR2## R.sup.1 is hydrogen or a lower alkyl group, and R.sup.2 is an unsubstituted or a lower-alkyl-, carboxyalkyl-, lower-alkoxy-, lower-alkoxycarbonyl- or halogen-substituted phenyl group or an unsubstituted or a halogen-substituted naphthyl group, and acid addition salts thereof are novel compounds exhibiting a specific enzyme-inhibitory activity to proteolytic enzymes and, therefore, they are useful as the therapeutic agent of diseases induced by abnormal activation of these enzymes. The above-mentioned compounds can be produced by subjecting a nitrocinnamic acid derivative represented by the formula: ##STR3## and a phenol derivative or a naphthol derivative represented by the formula: HO--R.sup.2 to an esterification in the conventional manner to obtain a nitrocinnamic ester derivative, then reducing the latter compound to obtain an aminophenylpropionic ester derivative and, if desired, reacting it with cyanamide to obtain a guanidino-phenylpropionic ester derivative and, if desired, further converting the reaction product to an acid addition salt.
