Fig. 7. Figure illustrating the 47 molecules utilized to evaluate the performance of DP4-AI. Molecules, AT3, TS3A, TS4 and NL1A have only have corresponding ¹H NMR data, all other molecules have both ¹H and ¹³C NMR data. The spectra for molecules JB7, JB11, JB5 and JB8 were taken in solvents methanol, benzene, DMSO and methanol respectively, whilst all others were taken in CDCl₃. Sources for the spectral data: AT1-3,^50,51 BYH1-2,⁵² JB1-13B,^53,54 TP1-4 (personal correspondence), TS1-4 (personal correspondence), OD1 (personal correspondence).
