This handbook offers authoratative information on how noncovalent and covalent templates can be effectively applied to control reaction rates as well as regio- and stereoselectivity. From the concepts of template control such as molecular imprinting, self-replication, and reversible tether-directed remote functionalization, the reader is led to template-based ring-closing reactions, oligomerizations, and multiple functionalizations and their application in the syntOrganic compoundsSynthesisPhysical organic chemistryOrganic compoundsSynthesis.Physical organic chemistry.541.35547.2Stang P.
