An Expeditious Synthetic Access to β-(<i>Z</i>)-[(1-Propynyl)amino]enones and β-[(<i>Z</i>)-(1-Propynyl)amino]enoates

Abstract

The silver nitrate promoted reaction of propargyl bromide with (Z)-4-amino-3-penten-2-ones and (Z)-3-amino-2-butenoates provides rapid access to β-(Z)-[(1-propynyl)amino]enones and β-[(Z)-(1-propynyl)amino]enoates respectively.
