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.

The Chemistry of Some Bicyclic Pyridinium Anhydrobases

The anhydrobase from 5,6,7,8-tetrahydro-2,4-diphenyl-1-p-tolylquinolinium reacts with C-, N-, and S-electrophiles to form adducts and new anhydrobases.The tautomeric structures of the adducts are deduced from spectral evidence.
