Pyridine derivatives
R 0380
Synthesis of 6-Bromomethyl-Substituted Derivatives of Pyridin-2(1H)-ones and
Reaction with Nucleophiles. — Radical bromination of pyridinone (IIIa) in
18- 132 Their
CHCl3 proceeds with subsequent lactonization [→(V)] of the intermediate bromomethyl derivative (IV), while bromination of (III) in AcOH leads to the oxidized form
of bromomethyl derivative (IV), i.e. compounds (VI). Compound (VIa) is used for the
preparation of several new aminomethyl-substituted pyridinones, thieno- and furopyridinones. — (KALME, Z. A.; ZHALUBOVSKIS, R. A.; SHMIDLERS, A.;
