Fig. 1: Procedure and characterizations of asymmetric transformation.

a Procedure of the asymmetric transformation. b UV-vis spectra of Au23 (yellow trace), (Rac)-LC1 (black trace), (R)-LC1 (red trace) and (S)-LC1 (blue trace). Inset: the photographs of Au23 and LC1 in DCM. c ESI-MS spectrum of LC1. Inset: the experimental (black trace) and calculated (red trace) isotope patterns. Source data are provided as a Source Data file.
