Synthesis of 5-substituted 4-aminoalkylpyrazol-3-ones (isoxazol-3-ones) from 3-acyllactams
Nenajdenko,Zakurdaev,Gololobov,Balenkova
, p. 220 - 225 (2005)
Structurally various 3-acyllactams act as 1,3-bielectrophiles in heterocyclization reactions with a variety of hydrazines and hydroxylamines to give aminoalkylpyrazolones and -isoxazol-ones in high yields.
