✦ Synopsis
Diastereoselective C3-elongation processes of N-tosyl-(l) and N-benzyI-N-tosyl-Lalaninal (2), using various allyl reagents and different reaction conditions, are described. A large difference between effects of the N-protecting groups replacing either one or two amino protons was observed.
