title: Modified guanidines as chiral auxiliaries.
abstract: Investigations on modified guanidines, prepared by newly developed methods, as potential chiral auxiliaries led to reasonable asymmetric induction not only in catalytic but also in stoichiometric asymmetric syntheses. These guanidine-mediated reactions may contribute to the development of green chemistry because of their possible application as re-cyclable (economically favored) and easily functionalizable (widely applicable) auxiliaries.
