Synthesis of fluorescent 3-benzoxazol-2-yl-coumarins
Twelve 3-benzoxazol-2-yl-coumarins (1-3) were synthesised by reacting various ortho-aminophenols with three coumarin-3-carboxylic acids either directly or by formation of the intermediate amide. The cyclodehydrating agent was polyphosphoric acid (PPA). The compounds were characterised by spectroscop...
