- Abstract
The Synthesis of Some 2 H-Pyran-2-one Derivatives Derivatives of 6-unsubstituted 2 H-pyran-2-one have been synthesized by several different methods. The 4-chloro-2 H-pyran-2-one ( 9) is the most important, since it serves as starting material for the synthesis of different 4-substituted 2 H-pyran-2-ones ( Scheme 2). Also described are simple transformations of cumalic-acid derivatives producing 5-(2,2-dichlorovinyl)-2 H-pyran-2-one ( 23), 2-oxo-2 H-pyran-2-carbonitrile ( 26), and 4,5-bis(trifluoromethyl)-2 H-pyran-2-one ( 32) ( Scheme 3 and 4).
