چکیده
|
In this work, efficient synthesis of 9-aryl-1,8-dioxo-octahydroxanthene derivatives from 1,3-cyclohexanediones and arylaldehydes in the presence of catalytic amount of melamine trisulfonic acid (msta) is described. the reaction is studied under thermal (solvent-free/80°c), microwave (solvent-free/180 w/90°c) and ultrasound (solvent/34-37 khz/350 w/60°c) conditions.
