Derivate von 4,5-Dihydroxypyridonen durch Ringerweiterung

The epimeric bromohydrins 13/14 as well as their ethers 5/6 rearrange in the presence of silver ions to the 5-hydroxypyridones 15 or their ketals 9 respectively.With the bromohydrin ethers 5/6a and b this transformation is effected also with sodium methox

Reactions of 5-Bromoalkylidene-3-pyrrolin-2-ones,1

The title compounds 1 react with sodium methoxide to give 5--3-pyrrolin-2-ones 2 by substitution and to yield 5-hydroxy-2-pyridones 3 by ring enlargement.The relative amounts of the products depend on the substituents and the alko
