—— | 3,4,6,7-tetrahydro-3,3,6,6-tetramethyl-9-(pyridin-2-yl)acridine-1,8(2H,5H,9H,10H)-dione | —— | C22H26N2O2 | 350.461 |
A practical protocol has been developed for the synthesis of 1,8-dioxo-octahydroxanthenes from aromatic aldehydes and 5,5-dimethylcyclohexane-1,3-dione under solvent-free conditions in the presence of wet 2,4,6-trichloro-1,3,5-triazine (TCT, cyanuric chloride). The desired products were obtained in high yields with a simple and environmentally benign procedure.
