Facile and efficient synthesis of 2-substituted-N1-carbethoxy-2, 3-dihydro-4(1H)-quinazolinones in fluorous solvent
摘要:
A facile, efficient and novel approach to access 2-substituted-N1-carbethoxy-2,3-dihydro-4(1H)-quinazolinones was developedby condensation of substituted N-carbethoxyanthranilamide with alkyl, aromatic or heteroaromatic aldehydes in the refluxing 2,2,2-trifluoroethanol or hexafluoroisopropanol using p-toluenesulfonic acid as catalyst.
