induced thermal fragmentative rearrangement. With the use of enantiopure pyrroline N-oxides derived from easily available chiral pool molecules, β-homoprolines were formed with high stereocontrol. The incorporation of one of these new cyclic β-amino acids into a simple tripeptide was also evaluated. In particular, the sterically hindered nitrogen atom of the highly substitutedpyrrolidine 30 was smoothly
