Chiral phosphoric acids (CPAs) have been used as efficient organocatalysts since the first examples were reported 18 years ago by Akiyama and Terada. Although they were originally developed for enantioselective additions to imines, a wide reaction scope has been demonstrated using this type of catalyst. In this review, the known applications of CPA for enantioselective additions to C![[double bond, length as m-dash]](http://www.rsc.org/images/entities/char_e001.gif)
O and CN bonds are covered.
