For simultaneous construction of the polyurethane backbone and the allyl si
de chains, Lewis acid-catalyzed three-component condensation reactions of c
arbonyl compounds, N-trimethylsilylcarbamates, and allyltrimethylsilane are
studied. The reaction of these three compounds took place in the presence
of a catalytic amount of TrClO4 at 0 degrees C to yield the corresponding N
-homoallylcarbamates in good yields. This reaction was also applied to the
synthesis of a polyurethane having the allyl side chains. (C) 2000 Elsevier
