Nucleophilic Displacements of N-Aryl and Heteroaryl Groups. Part 1. Pyrylium-mediated Transformation of Anilines into Phenols

Aromatic amines with 2,4-diphenyl-5,6,7,8-tetrahydrochromenylium trifluoromethanesulphonate (5) gave the corresponding pyridinium salts (6; R = aryl) which were converted by base into the anhydrobases (7).Benzoyl chloride converted (7) into the new pyridinium anhydrobases (9).These anhydrobases (9) rearrangement at 150 deg C into the isomeric phenol enol ethers (10) which were readily hydrolysed to yield the corresponding phenols.The mechanistic and synthetic significance of the results are assessed.
