| titleOfInvention | PROCEDURE FOR THE OBTAINING OF NITROBENZALDEHIDE DERIVATIVES. |
| abstract | PROCEDURE FOR THE OBTAINING OF NITROBENZALDEHYDE DERIVATIVES (I) WHERE THE NITRO GROUP CAN BE IN ANY POSITION, OF THE RING AND R MAY BE H, ALKYL CSI1-4 SC, ALCOXI CSI1-4 SC, CIANO, HALOGENO. THE PROCEDURE INCLUDES (A) THE FORMATION OF A DINITROESTILBENE (III) BY DEHYDROHALOGENATION / DIMERIZATION OF A NITROBENCIL CHLORIDE (II) IN THE PRESENCE OF A BASE AND IN AN ALCOHOLIC ENVIRONMENT, AND (B) THE OXIDATION OF THE DINITROSTILBENE (III) THE COMPOUNDS (I). NITROBENCIL CHLORIDES (II) CAN BE OBTAINED BY CHLORINATION OF THE CORRESPONDENTS DERIVED FROM NITROTOLUENE (IV), SO THESE THESE COMPOUNDS (IV) CAN BE USED IN THE SYNTHESIS OF COMPOUNDS (I). O-NITROBENZALDEHYDE MAY BE USED AS AN INTERMEDIATE OF SYNTHESIS OF BENZODIAZEPINE DERIVATIVES AND OF 4- (2 '' - NITROFENIL) -1,4-DIHIDROPIRIDINAS OF PHARMACEUTICAL INTEREST FOR ITS USE AS A CORONARY DILATOR AND HYPOTORATOR. |
