Abstract

1296753 6,7 - Methylenedioxy - oxocinnoline- 3-carboxylic acids ELI LILLY & CO 2 Feb 1970 [4,Feb 1969 29 Dec 1969] 4817/70 Heading C2C Novel 6,7 - methylenedioxy - oxocinnoline-3- carboxylic acids having the structure: where R is methyl, ethyl, n-propyl, isopropyl, n-butyl, vinyl or allyl and the cationic salts thereof formed with an alkali metal, an alkaline earth metal, ammonia or amines having a pKa greater than 7À5 may be prepared by a six or seven step synthesis from 21-nitro-4<SP>1</SP>,5<SP>1</SP>-methylenedioxyacetophenone in which (1) the nitro group is reduced to amino, (2) the amino group is diazotized and cyclized to yield 6,7-methylenedioxy cinnoline-4-ol, (3) substitution of bromine at the 3 position, (4) conversion of bromo to cyano, (5) alkylating at the 1 position to yield II in which R is as above excepting vinyl, but in addition is #-hydroxy ethyl followed by, (6) hydrolysis of the cyano group to give I and optionally when R is vinyl, (7) dehydration of the #-hydroxyethyl group substituted in step 5 above. The novel compounds II are the subject of Divisional Application 17320/72. Pharmaceutical compositions of the compounds I with the usual excipients show microbial activity when administered orally or parenterally. The compounds may also be used as the active ingredient for antimicrobial activity in agricultural formulations.
