2-Aza 1,3-dienes: a new and simple method for the synthesis of functionalized pyridine derivatives
摘要:
The synthesis of 4(1H)-pyridones and 4-chloropyridines from 2-aza 1,3-dienes is described, using carbonic acid derivatives. The process involves a [5 + 1] heterocyclization reaction, with formation of two new carbon-carbon bonds.
