| titleOfInvention | A PROCEDURE FOR THE PREPARATION OF NEW SPIRO-3-AZOLINDIONAS. |
| abstract | PROCEDURE FOR THE PREPARATION OF ESPIRO-3-HETEROAZOLIDINDIONAS. CONSISTENT IN REACTING A COMPOUND OF FORMULA (II), AT A TEMPERATURE INCLUDING BETWEEN 0 AND 60 C, WITH A PERFLUORCARBOXYLIMINE IN A NON-REACTIVE HALOGENATED SOLVENT (CHLOROFORM); THEN, AN IN SITU HALOGENATION IS PERFORMED WITH A MOLECULAR HALOGEN IN A SUITABLE SOLVENT (LOWER CARBOXYL ACID), USING A MINERAL ACID (HYDROBRIC ACID) AS THE CATALYST AT A TEMPERATURE UNDERSTOOD BETWEEN 4 WATER AND 100 C. AT PH INCLUDED BETWEEN 1 AND 7 AT TEMPERATURE 0-60 C. THE RESULTING ALCOHOL IS SUBSEQUENTLY OXIDIZED WITH CHROME TRIOXIDE IN ACETIC ACID AT TEMPERATURE 0-60 C. U REPRESENTS OXYGEN, SULFUR OR SUBSTITUTED NITROGEN; R HYDROGEN OR LOWER ALKYL; W CARBONYL OR HYDROXIMETHYLENE; X HYDROGEN, HALOGEN OR LOWER ALKYL, E Y Y Z HALOGEN, NITRO, ALKYL OR ALCOXY. OF APPLICATION IN THE TREATMENT OF DIABETIC CATARACTS, RETINOPATHIES AND NEUROPATHIES. |
