SYNTHESIS OF HETEROCYCLIC COMPOUNDS BY THE SKRAUP REACTION OF AMINO-9H-XANTHEN-9-ONES
Fujiwara, Hidetoshi,Okabayashi, Ichizo
, p. 541 - 550 (2007/10/02)
The Skraup reaction of amino-9H-xanthen-9-ones was conducted in the presence of glycerol, fuming sulfuric acid, nitrobenzene, iron (II) sulfate and boric acid. 1-Amino-9-xanthen-9-one gave 12H-benzopyranoquinolin-12-one. 2- And 3-amino-9H-xanthe
