Easy access to pyranoacridines, pyranoxanthenes, and arylchromenes through a domino reaction
A series of pyrano[2,3,4-kl]acridines has been synthesized through an unprecedented domino reaction involving1-hydroxy-3-methoxy-10-methylacridone and Grignard reagents. This method has been successfully applied to xanthone, anthracenone, and benzophenone
Reduction of 1-substituted anthraquinones to 1- and 4-substituted anthrones
The regioselectivity of reduction of 1-substituted anthraquinones to 1 - or 4-substituted anthrones is determined by both the nature of the substituent and the type of the reducing system used.
