Abstract:
This tutorial review presents a description of the controlling elements of intermolecular C-H functionalization by means of C-H insertion by donor/acceptor rhodium carbenes. These rhodium carbenes, readily derived from the combination of diazo compounds with dirhodium(ii) catalysts, are sufficiently reactive to undergo a wide range of C-H insertions. They are also capable of highly selective reactions, controlled by a combination of steric and electronic factors. An overview of the structural factors that influence site selectivity will be given, followed by a description of the exceptional diastereo- and enantioselectivity that can be achieved. Several examples will be shown of how this methodology can be applied to streamline the synthesis of natural products and pharmaceutical targets.

02:36Regioselectivity and Stereochemistry of Hydroboration
Hydroboration proceeds in a concerted fashion with the attack of borane on the π bond, giving a cyclic four-centered transition state. The –BH2 group is bonded to the less substituted carbon and –H to the more substituted carbon. The concerted nature requires the simultaneous addition of –H and –BH2 across the same face of the alkene giving syn stereochemistry.
02:17Regioselectivity of Electrophilic Additions to Alkenes: Markovnikov's Rule
The hydrohalogenation of an unsymmetrical alkene can yield two haloalkane products, depending on which vinylic carbon takes up the halogen. However, one product usually predominates, where hydrogen adds to the vinylic carbon bearing the...

02:17Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
