Abstract We report the synthesis of several enantiopure pyrrolidine derivatives containing a β-amino acid moiety. These novel chiral compounds were prepared through stereospecific chlorosulfonyl isocyanate (CSI) addition to the readily available, natural terpene (+)-α-pinene. Coupling of N-Boc-protected β-amino acidderivatives with various bulky amines and aminoacids using the mixed anhydride activation
