different 2-substituted 8-methoxy-1-naphthamides. The enantiomers of atropisomeric 8-methoxy-1-naphthamides were prepared through a chemical resolution process, and their absolutestereochemistry was determined by X-ray crystal structural analysis. It was found that the linkage between crotonate and the C2 position of 8-methoxy-1-naphthamides remarkably influenced the efficiency of remote chirality transfer
