Fig. 4: Statistical analysis of the 1430 screened asymmetric reactions from the perspective of organocatalysts, photocatalysts and substrates.

a–c Violin plots of ee values with different (a) organocatalysts, (b) photocatalysts and (c) substrates. d–f Violin plots of relative MS yields with different (d) organocatalysts, (e) photocatalysts and (f) substrates. The median is represented with the middle solid line, and the interquartile ranges are represented by the outer dashed lines. The bar chart at the top of each panel shows the comparison of medians.
