, p. 2773 - 2774 (2007/10/02)
The potassium enolate of 4-methoxy-3-buten-2-one reacts with acid chlorides anhydrides and acylimidazoles by C-acylation and in situ cyclization to afford 2-substituted γ-pyrones directly.
A CONVENIENT SYNTHESIS OF SUBSTITUTED γ-PYRONES
Koreeda, Masato,Akagi, Hiroshi
, p. 1197 - 1200 (2007/10/02)
An efficient and general synthetic method for various 2-mono- and 2,6-disubstituted γ-pyrones has been developed.This utilizes the C-acylation (70-85percent) of β-methoxy-α,β-enone lithium enolates 4 by acid chlorides 3 followed by the acid-catalyzed cycl
