Synthesis of Some New Derivatives of 4H-Pyran- 4-One
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2014, Vol 8, Issue 10
Abstract
Two different Products were obtained from reactions of 2,6-bis(bromomethyl)-4-oxo-4H-pyran-3,5-dicarboxylic acid diethyl ester(5) and KSCN depend on their mole ratio : 2,6- bis(thiocyanatomethyl) (6) and 2,6-bis(isothiocyanatomethyl) (7) derivatives . 2,6-Bis (aminomethyl) (8) was prepared by treatment of 5 with KOCN followed by hydrolysis. 2,6-Bis(azidomethyl) (9) synthesized by means of reaction of 5 with NaN3 . Treatment of 4-pyrone (4) with excess Bromine led to 2-dibromomethyl-6-tribromomethyl-4-oxo-4H-pyran-3,5-dicarboxylic acid diethylester (10).
