摘要
A new type of axiallychiral sulfonic acid was developed.The synthesisis based on cheap commercially available materials and a practicalmethod for optical resolution via diastereomeric salt formation, whichcan provide both enantiomers. Eleven benzoimidazolylnaphthalenesulfonicacids were prepared and four of them were isolated as pure and stableatropisomers. Moreover, several of these sulfonic acids were transformedinto triflyl imides to further expand the range of dissociation constants.
