Synthesis of β-disubstituted β-amino isoxazolyl ketones by addition of ketimines with isoxazolyl methyl ketone enolates

A series of β-disubstituted N-sulfinyl β-amino isoxazolyl ketones has been prepared by addition of tert-butanesulfinyl ketimines with the n-BuLi-generated enolates of isoxazolyl methyl ketones.
