Fig. 2: Reaction rate constants.
From: Heterochiral coupling to bilateral β-turn structured azapeptides bearing two remote chiral centers

a The reactions between L-intermediate (L-AcFTUNCS) and L-AcFN2H3 or D-AcFN2H3, yielding homochiral L,L-AcFTU2 and heterochiral L,D-AcFTU2, respectively. b The reaction rate constants kL,L and kL,D in MeCN versus reaction temperature.
