An efficient and practical method for optical resolution of axially chiral biaryl dials using enantiomeric tert-butanesulfinamide as resolving agent was developed. The approach offers a very convenient and straightforward access to versatile enantiomericallypure C2-symmetric biaryl dials in good yields. With the obtained axially chiral dials, stereoselective synthesis of a series of cyclic trans-1
