Modular syntheses of isoxazoloazepinones and pyrazoloazepinones
Adamo, Mauro F.A.,Duffy, Eleanor F.,Donati, Donato,Sarti-Fantoni, Piero
, p. 2684 - 2688 (2007/10/03)
Herein we described an optimised synthesis of isoxazoloazepinone and novel heterocycle pyrazoloazepinone. These syntheses are modular in nature and fast to execute. The title compounds were obtained pure without the intervention of chromatography.
