Definitions
- the present invention relates to compounds of formula:
- Ri represents a radical -alk-CN, -alk-COOH, -alk-Het, -alk-PO 3 H 2 or -alk-CO-NH-SO 2 R 2 ,
- R 2 represents an alkyl or phenyl radical
- alk represents an alkyl radical
- Het represents a saturated or unsaturated mono or polycyclic heterocycle containing 1 to 9 carbon atoms and one or more heteroatoms chosen from O, S, N, the heterocycle being optionally substituted by one or more alkyl, phenyl or phenylalkyl radicals,
- R T when R represents a hydrogen atom or a radical -COOH or -PO 3 H 2 , R T cannot represent -alk-COOH. Unless otherwise stated, in the definitions above and those which follow, the alkyl and alkoxy radicals contain 1 to 6 carbon atoms in a straight or branched chain.
- the substituent Ri is in position -8 or -9.
- Het represents a tetrazole-5-yl ring.
- racemates, enantiomers and diastereoisomers of the compounds of formula (I) for which R represents a radical -alk-COOH and / or R1 represents a radical -alk-CN, -alk-COOH, -alk-Het, -alk-PO 3 H 2 or -alk-CO-NH-S0 2 R 2 are also part of the invention.
- the compounds of formula (I) can be prepared by cyclization, either in the presence of ammonium acetate, or in the presence of ammonia, or in the presence of ammonium acetate and ammonia, of a derivative of formula :
- Rb represents a radical -alk-CN, -alk-COOalk ', -alk-PO (Oalk') 2) -alk-CO-NH-SO 2 R 2 or -alk-Het
- alk and alk ' represent an alkyl radical
- R 2 and Het have the same meanings as in formula (I), followed by hydrolysis.
- Het represents a tetrazolyl-5-yl radical
- Rb represents a -alk-tetrazole-5-yl radical in which the tetrazole is substituted in position -1 or -2 with a benzyl radical and then debenzylate the final product.
- This cyclization is preferably carried out in an organic acid such as acetic acid, at the boiling temperature of the reaction medium, optionally in the presence of ammonia in solution in a lower aliphatic alcohol such as methanol.
- the hydrolysis of the -COOalk, -PO (Oalk) 2 functions and debenzylation are carried out by any known method making it possible to pass from an ester to the corresponding acid or from a dialkylphosphonate to the corresponding phosphonic acid or to debenzyler without modifying the rest of the molecule.
- the operation is carried out by means of a mineral acid such as hydrobromic acid or hydrochloric acid, at a temperature of 100 ° C.
- Rb has the same meanings as in formula (II) or represents a radical -alk-Het 'for which Het' represents a tetrazole-5-yl radical substituted in position -1 or -2 by a benzyl radical and Hal represents a halogen atom (preferably chlorine or bromine) on a derivative of formula:
