Abstract
Treatment of 6-trifluoro(trichloro)methyl-2,3-dihydro-4-pyrones with a mmonia gives -amino-1,1,1-trifluoro(trichloro)-6-methylhepta-3, 5-dien -2-ones. Under similar conditions 1-trifluoro-2-hydroxy-6-methylhepta- 2,5-dien-4-one and -1,1,1-trifluoro-2-hydroxy-6-methylhept-2-en-4-one cyclize into dimethyl-6-trifluoromethyl-2,3-dihydro-4-pyridone.
