Abstract
A product C11H14N2O4 obtained in the reaction of ethyl acetoacetate and hydroxylamine has been identified as (II), and evidence is presented that it was formed through 4-isopropylidene-3-methylisoxazol-5-one (III). A Michael reaction of 4-benzylidene-3-methylisoxazol-5-one (VII) is also recorded.Keywords
