A Facile Synthesis of 3-Acylaminocoumarins

Tripathy, Pradeep K.,Mukerjee, Arya K.

, p. 61 - 62 (2007/10/02)

2-Methyl/phenyl-2-oxazolin-5-ones (2a,b), generated by cyclising aceturic and hippuric acids respectively with benzenesulphonyl chloride and triethylamine in benzene, undergo condensation with salicylaldehyde to give 3-acetyl/benzoylaminocoumarins (4a,b) which afford 3-aminocoumarin (5) on acid hydrolysis.Hydrolysis of 4b with KOH gives 3-hydroxycoumarin (6) and/or 2-benzoylamino-o-hydroxycinnamic acid (9).
