Simple, Efficient Procedure for the Synthesis of Benzopyrano[2,3-c]isoxazoles
摘要:
Synthesis of 3-imino-benzopyrano[2,3-c]isoxazoles was successfully performed using heterorocyclization of 2-imino-2H-1-benzopyrano 3-carbonitrile derivatives with hydroxylamine. The synthesized compounds were characterized by infrared, H-1 NMR, C-13 NMR, mass spectroscopy, and elemental analysis.
