The present invention relates to an aromatic substituted pentadienoic acid amides and there use in combination of specific amounts of aromatic amides i.e. 4-alkyl-5-(substituted phenyl)-2(E),4(E)-pentadienoic acid amides, its geometrical isomers or their dihydro or tetrahydro derivatives and an anti-infective drug useful in potentiating the bioefficacy of antiinfective drug. The combination of the present invention is useful in the treatment of certain infections and disease at lower concentration of anti-infectives necessary to inhibit the growth of microbial strains and may also find applications in reducing the resistance in microorganisms.

Substituted hexa-3,5-dienoic acid methyl esters (2) were conveniently prepared in one step by 1,2-carbonyl transposition of the corresponding dienones (1) using lead(IV) acetate and boron trifluoride–diethyl ether in benzene at room temperature.

3-arylpropanoic acids or halides requires the use of noncatalytic acid promoters. In the presence of 5−10 mol % FeCl3, in situ generated dimethyl acetals of (E)-2-alkylcinnamaldehydes cyclize to 1-methoxy-2-alkyl-1H-indenes in good-to-high yields. The 1-methoxyindenes were converted in high yield into 2-alkylindanones by treatment with triethylamine, to effect isomerization to the isomeric enol ethers
The invention relates to compounds of antihypertensive and antithrombotic activity of the formula or its pharmaceutically acceptable salt: ##STR1## wherein R.sup.1 is hydrogen, lower alkyl, or lower alkoxyphenyl, R.sup.2 is hydrogen or lower alkyl, R.sup.4 is lower alkyl, R.sup.6 is hydrogen or lower alkyl, R.sup.7 is lower alkyl which is optionally substituted by hydroxy or lower alkanoyloxy, and R.sup.10 is hydrogen or lower alkyl which is optionally substituted by carboxy or esterified carboxy.
