A convenient synthesis of 4-alkoxylated isoindolin-1-ones

A short synthesis of 4-alkoxylated isoindolin-1-ones based upon the S NAr reaction applied to phosphorylated 2-methoxybenzamides followed by alkaline cleavage of the phosphoryl auxiliary is reported.

The Chemistry of 2H-3,1-Benzoxazine-2,4(1H)-dione (Isatoic Anhydride). 21. A Mild Process For The Preparation of 10-Alkyl-9-acridanones And It's Application To The Synthesis of Acridone Alkaloids

10-Substituted-9-acridanones are readily prepared by the reaction of the corresponding isatoic anhydride with the lithium enolate of 2-cyclohexen-1-one.The initially formed product, the 1,2-dihydroacridone need not be purified but can be aromatized directly with DDQ to the desired acridone.This methodology is applicable to the synthesis of acridone natural products.Two alkaloids, 1,2,3-trimethoxy-10-methylacridone (9) and evoxanthine (10), were prepared from 4,5,6-trimethoxy-N-methylisatoic anhydride and 6-methoxy-4,5-methylenedioxy-N-methylisatoic anhydride respectively.In these trioxygenated systems, palladium-on-charcoal must be used to aromatize the penultimate intermediate.

Synthesis of the Yeast Antioxidant Benzofuran and Analogues

2-(6-Hydroxy-2-methoxy-3,4-methylenedioxyphenyl)benzofuran, the active antioxidant which occurs in yeasts, and related 2-arylbenzofurans have been synthesized by a convergent route.The key step involves benzofuran formation by an intramolecular Wittig reaction.
