6- chromone

The fragmentation pattern of isoxazoles on electron impact has been well studied. It has been used as an important tool for the structural assignment of isoxazoles obtained from the reaction of chromones with hydroxylamine 79MI41600, 77JOC1356). For example, the structures of the isoxazoles (387) and (388) were assigned on the basis of their fragmentation patterns. Ions at mje 121 (100%) and mje 93 (19.8%) were expected, and indeed observed, for the isoxazole (388), and an ion at mje 132 (39.5%>) was similarly predicted and observed for the isoxazole (387). [Pg.79]

The reaction of hydroxylamine with 2-substituted chromones (392) where R = Me, Ph (76MI41601) or CO2H (79MI41600) gave exclusively 5-(o-hydroxyphenyl)isoxazoles (393). [Pg.79]
