| titleOfInvention | PROCEDURE FOR THE OBTAINING OF NITROBENZALDEHIDE DERIVATIVES. |
| abstract | PROCEDURE FOR OBTAINING NITROBENZALDEHYDE DERIVATIVES (I) WHERE THE NITRO GROUP CAN BE IN ANY POSITION, THE Y R RING CAN BE H, ALKYL CSI1-4 SC, ALCOXY CSI1-4 SC, CYANO, HALOGEN. THE PROCEDURE INCLUDES (A) THE FORMATION OF A DINITROSTILBENE (III) BY DEHYDROHALOGENATION/DIMERIZATION OF A NITROBENZYL CHLORIDE (II) IN THE PRESENCE OF A BASE AND IN AN ALCOHOLIC MEDIUM AND (B) THE OXIDATION OF THE DINITROSTYLBENE (III), TO GIVE THE COMPOUNDS (I). NITROBENZYL CHLORIDES (II) CAN BE OBTAINED BY CHLORINATION OF THE CORRESPONDING DERIVATIVES OF NITROTOLUENES (IV), SO THESE COMPOUNDS (IV) CAN BE USED IN THE SYNTHESIS OF COMPOUNDS (I). O-NITROBENZALDEHYDE CAN BE USED AS AN INTERMEDIATE FOR THE SYNTHESIS OF BENZODIAZEPINE DERIVATIVES AND 4-(2''-NITROPHENYL)-1,4-DIHYDROPYRIDINES OF PHARMACEUTICAL INTEREST DUE TO ITS USEFULNESS AS A CORONARY DILATOR AND HYPOTENSOR. |
