A series of nonracemizable ligands are synthesized for the direct chemical resolution of various unprotected β3‐amino acids with high enantioselectivity and yields. One of the obtained free enantiomerically pure β‐amino acids can be applied directly as a starting material for the synthesis of the anti‐HIV drug maraviroc in an overall yield of 49 % in six steps.
