Synthesizes fluorescent pyrazoles from isoxazoles, indicating a new eco-friendly method for developing derivatives.
A TFA-mediated MW-assisted synthesis of 5-amino-3-(hetero)arylpyrazoles via 5-(hetero)aryl-isoxazoles as 1,3-bis-electrophylic substrates under eco-friendly conditions was developed, and the photophysics of some fluorescent derivatives were studied.
