Abstract

BACKGROUND: PHOSPHONATES HAVE IMPORTANT APPLICATIONS IN ORGANIC SYNTHESIS [1], AND BIOLOGICAL APPLICATIONS [2]. THEN, STABLE DERIVATIVES OF OXAPHOSPHAPHENANTHRENES WERE PREPARED USING OF DIALKYL ACETYLENEDICARBOXYLATE WITH 3-BROMO-2-NAPHTHOL IN THE PRESENCE OF TRIMETHYL OR TRIPHENYL PHOSPHITE IN GOOD YIELDS.METHODS: TO A MAGNETICALLY STIRRED SOLUTION OF DIALKYL ACETHYLENEDICARBOXYLATE (2 MMOL) AND 3-BROMO-2-NAPHTHOL (2 MMOL) IN 20 CM3 CH3CN WAS ADDED TRIPHENYL PHOSPHITE OR TRIMETHYL PHOSPHITE (2 MMOL) UNDER MICROWAVE CONDITIONS. THE REACTION MIXTURE WAS THEN STIRRED FOR 6H. AFTER COMPLETION OF REACTION (MONITORED BY TLC), THE MIXTURE OF REACTION WAS PURIFIED BY PREPARATIVE TLC ON SILICA GEL COLUMN CHROMATOGRAPHY USING N-HEXANE-ETOAC AS ELUENT TO GIVE PRODUCTS.RESULTS: THE RESULTS OF REACTION OF DIALKYL ACETYLENEDICARBOXYLATE 2, 3-BROMO-2-NAPHTHOL 1 AND TRIMETHYL OR TRIPHENYL PHOSPHITE LEADS TO 3-BROMO-4H-1-OXA-PHOSPHAPHENANTHRENE-3, 4-DICARBOXYLATE DERIVATIVES 4 IN EXCELLENT YIELDS.
