Mechanistic Investigation on Potassium Amide-Catalyzed Benzylic C–H Bond Addition of Alkylpyridines to Styrenes

Organometallics, Год журнала: 2024, Номер 43(4), С. 526 - 531

The catalytic C–H bond addition of alkylpyridines to olefins represents one the most efficient approaches alkyl-substituted pyridine derivatives with 100% atom-economy efficiency. Various catalysts including late transition metal, early and s-block metal complexes displayed rich versatile activity. Potassium amide could selectively achieve benzylic alkylation alkylpyridines, displaying distinct activity regioselectivity. Here, mechanistic investigation via both kinetic experiments DFT calculations revealed dimer structure potassium confirmed a deprotonative functionalization process.

Abstract A new method for the synthesis of pyridine‐ and quinoline‐ N ‐oxides containing a ureido or carbamoyl fragment in position 2 has been developed. This concluded oxidation relatively readily available substituted , ‐dimethyl‐ ′‐(pyridine‐2‐yl)ureas to corresponding ‐oxides, followed by modification dimethylureide moiety. Being heated 90 °C presence amines solution DMF chlorobenzene, ‐oxide ′‐(pyridine‐2‐yl)urea undergoes transamination reaction without loss function. produces ‐alkyl/aryl‐ N’ ‐(pyridine‐2‐yl)ureas 24–99 % yields, (about 30 examples). Values NH protons chemical shifts are good criterion selectivity reaction. The is also applicable ureas pyridine ring quinoline congener. ‐Oxides pyridine/quinoline‐containing carbamates can be similarly prepared heating ′‐(pyridine‐2‐yl)/(quinoline‐2‐yl)‐urea an appropriate alcohol at 120 °C.
