para-Toluenesulfinamide (also known as p-toluenesulfinamide or Davis' sulfinamide/auxiliary) is an organosulfur compound and a member of the class of sulfinamides. Both enantiomeric forms are commercially available and are used in asymmetric synthesis as chiral auxiliaries.[1][2][3] This compound was first introduced in 1997 by Franklin A. Davis et al.[4]
