Abstract
The synthesis and reactivity studies of 4-hydroxy-6-methyl-3-(5-phenyl-2E,4E-pentadien-1-oyl)-2H-pyran-2-one 2 with nucleophiles are reported. Reactions of 2 with hydrazine derivatives gave new pyrazole-type com pounds while the reaction with ortho-phenylenediamines yielded 1,5-benzodiazepines. The reaction of 2 with ethylamine implies the 2H-pyran-2-one ring opening and the formation of a strong conjugated compound 3.
