Base-induced cyclization of trimethoxy-o-aroyldiphenylphosphoryl methylbenzamide: A formal synthesis of (±)Cherylline and (±)Cherylline dimethylether

The trimethoxy-o-aroyldiphenylphosphorylmethylbenzamide 9 can be cyclized by treatment with KHMDS; the procedure has been employed to synthesize (±)Cherylline 1 and its dimethylether 2.

OXIDATION OF 1-ARYL-6,7-DIMETHOXYISOCHROMANS WITH CHROMIUM(VI) OXIDE IN ACETIC ACID: A NEW SYNTHETIC PATHWAY TO 2-AROYL-4,5-DIMETHOXYBENZALDEHYDES AND 2-ACETYL-4,5-DIMETHOXYBENZOPHENONES

The oxidation of 1-aryl-6,7-dimethoxyisochromans with chromium(VI) oxide in acetic acid does not give the expected 2-aroylphenylacetic acids, but instead leads to a mixture consisting chiefly of 2-aroyl-4,5-dimethoxybenzaldehydes and of the corresponding
