1,2,3,4,5,6,7,8-Octahydro-3,3,6,6-tetramethylacridine-1,8-dione

In the title compound, C17H21NO2, the central pyridine ring is almost planar and the outer rings are half-chairs. The O atoms of the keto groups deviate significantly from the mean plane passing through their corresponding rings. The molecule contains a pseudo-mirror plane which passes through the central N and C atoms and the molecule is slightly folded along an axis passing through the same atoms. The dihedral angle between the outer rings is 6.5 (2)°. The packing is stabilized by an intermolecular C-H...O hydrogen bond.

Photooxidation of acridine(1,8)dione dyes: Flash photolysis investigation of the mechanistic details

Photolysis of the acridinedione dyes leads to the formation of different products depending on the substitutents. The cationic radical and the solvated electron are the primary photoproducts. Flash photolysis studies show that the solvated electron subsequently reacts with the ground state molecule to give the anion radical. The enolic form of the cation radical is also observed as an intermediate. The anionic radical and enolic form of the cation radical absorb at around 480 and 550 nm respectively. Subsequently these radicals result in ketyl and carbon-centered radicals respectively. The carbon-centered radical absorbs at 650 nm.

One-Pot Synthesis of Hantzsch Pyridines via NH4I Promoted Condensation of 1,3-Dicarbonyl Compounds with DMSO and NH4OAc

A one-pot synthesis of Hantzsch pyridines was achieved through NH4I-promoted condensation of 1,3-dicarbonyl compounds with DMSO and NH4OAc, in which the C4 of the pyridine rings was derived from DMSO and the nitrogen atom resulted from NH4OAc and NH4I. The target product could be obtained in moderate to excellent yields.
