A simple synthetic method for fluorine-containing 4H-pyrano[3,2- d]isoxazoles and 4-cyanoethyl-isoxazoles from 5-trifluoroacetyl-2-methoxy- 3,4-dihydro-2H-pyran with hydroxylamine hydrochloride

5-Trifluoroacetyl-2-methoxy-3,4-dihydro-2H-pyran (1), prepared from 2- methoxy-3,4-dihydro-2H-pyran with trifluoroacetic anhydride, reacted cleanly with hydroxylamine hydrochloride in alcohol to give fluorine-containing 4H- pyrano[3,2-d]isoxazoles (2a-g) or 4-cyanoethyldihydroisoxazoles (3) selectively in moderate to high yields. Further conversion of 3 into 4- cyanoethylisoxazoles (4) was also described.

This study reports a simple, fast, and efficient method for the synthesis of a new series of 1-arylethyl-2-arylethylamino-5-trifluoroacetyl-1,2,3,4-tetrahydropyridines and related compounds from the reaction of 2-alkoxy-5-trifluoroacetyl-3,4-dihydro-2H-py
Highly chemoselective synthesis of 6-Alkoxy-l-aIkyl(aryl)-3- trifluoroaeetyl-1,4,5,6 tetrahydropyridlines and 1-Alkyl(aryl)-6-anino-3- trifluoroacetyl-1,4,5,6-tetrahydropyridines
