We report the development of a method for room-temperature C-H hydroxymethylation of heteroarenes. A key enabling advance in this work was achieved by implementing visible light photoredox catalysis that proved to be applicable to many classes of heteroarenes and tolerant of diverse functional groups found in druglike molecules.
On the thermally induced rearrangement of 2-alkoxypyridines to N-alkylpyridones

Analogues of 2-methoxypyridine undergo rearrangement to N-methylpyridones under flash vacuum pyrolysis (FVP) conditions. Ethoxy derivatives undergo competitive ethyl migration and elimination of ethylene. Analogues of 4-methoxypyridine do not undergo rearrangement under FVP conditions, but demethylation on silica may occur. The ease of rearrangement follows the basicity of the alkoxyhetarene to some extent. The vapour-phase rearrangements have been contrasted to condensed-phase pyrolyses. and a four-centre transition state for the former is supported by computation. The rearrangement allows structural assignment to the two products from the reaction of 2,4-dichloroquinoline with pyrrolidine.

Experimental ionization potentials of quinoline 1 and substituted quinolines: 6-methylquinoline 2, 2,6-dimethylquinoline 3, 6-methoxyquinoline 4, 3-bromoquinoline 5, 2-chloro-4-methylquinoline 6, 4-hydroxyquinoline 7, 4-hydroxy-2-methylquinoline 8, 2-hydroxy-4-methylquinoline 9, 4-methoxyquinoline 10, 4- methoxy-2-methylquinoline 11, 2-methoxy-4-methylquinoline 12, were measured by photoelectron spectroscopy. Molecular orbital energies of the same derivatives were calculated by the Austin Method 1. The assignments of the bands of the photoelectron spectra were done with the aid of the theoretical calculations and on the basis of the substituent effects. For quinolines 1-6 a good agreement was found between the experimental ionization potentials and the calculated orbital energies.
Alkylation of 2-, 4-, and 8-Trialkylsiloxyquinolines by Methyl Iodide

Trimethyl- and triethylsilyl ethers of 2-, 4-, and 8-hydroxyquinolines have been prepared.The alkylation of these siloxyquinolines by methyl iodide has been studied.In the case of 4-trimethylsiloxyquinaldine, it has been established that both N- and O-alkylation products are formed.
