Abstract The reactivity of Grignard reagents with UNCAs (UrethaneN-protected Carboxyanhydrides of Amino acids)is described. We observed that, depending on the method ofaddition of the organometallic compounds, the reactionproceeded differently:(i) when the UNCA was added to the Grignard reagent, weobtained a mixture of five different products whichwere all identified; and (ii) when the organometallic reagent was added to theUNCA, we also obtained a mixture of the same productsbut in different proportions, with the major componentcorresponding to the urethane N-protected N-acyl aminoacid derivative.
