Available in PDF, EPUB and Kindle. Book excerpt: Chapter 1. A sequence of research projects beginning with studies in diastereoselective C-H bond functionalization applied to the synthesis of ( - )-incarvaillateine to the Rh(III) catalyzed arylation of imines, are described. Some theory and mechanistic considerations are discussed in relation to the genesis of these projects. Research directions are summarized and rationalized. Chapter 2. The synthesis of ( - )-incarvillateine utilizing a key C-H bond alkylation step is described as a means to highlight the synthetic utility of a newly reported olefinic C-H bond functionalization methodology. Elements of diastereoselectivity are also explored in the key step which allows for the concise, stereoselective synthesis of the natural product. Progress in the area of enantioselective C-H alkylations are also summarized as it applies to the synthesis of other natural products. Chapter 3. A method for the enantioselective cyclization of N-allylimidazoles is developed. The reaction is thought to proceed via a novel, reactive N-heterocyclic carbene. High enantioselectivities are achieved, which is unusual in view of the elevated temperatures of the reaction. Chapter 4. The first general method for the oxidative coupling of unactivated alkenes via C-H bond functionalization is reported using a methyl oxime directing group. A silver abstractor is important to obtain reactivity. Several functional groups are compatible with the reaction and no precautions to exclude air are required. Chapter 5. A rare example of C-H activation and intermolecular coupling to N-protected-imines is achieved using a cationic Rh(III) catalyst. The reaction is directed by pyridines and related heterocycles and produces a variety of aryl-branched amines. The reaction accommodates several reactive functional groups and is mild enough to even couple with sensitive alkyl N-sulfonyl-imines.

Available in PDF, EPUB and Kindle. Book excerpt: Once considered the 'holy grail' of organometallic chemistry, synthetically useful reactions employing C-H bond activation have increasingly been developed and applied to natural product and drug synthesis over the past decade. The ubiquity and relative low cost of hydrocarbons makes C-H bond functionalization an attractive alternative to classical C-C bond forming reactions such as cross-coupling, which require organohalides and organometallic reagents. In addition to providing an atom economical alternative to standard cross - coupling strategies, C-H bond functionalization also reduces the production of toxic by-products, thereby contributing to the growing field of reactions with decreased environmental impact. In the area of C-C bond forming reactions that proceed via a C-H activation mechanism, rhodium catalysts stand out for their functional group tolerance and wide range of synthetic utility. Over the course of the last decade, many Rh-catalyzed methods for heteroatom-directed C-H bond functionalization have been reported and will be the focus of this review. Material appearing in the literature prior to 2001 has been reviewed previously and will only be introduced as background when necessary. The synthesis of complex molecules from relatively simple precursors has long been a goal for many organic chemists. The ability to selectively functionalize a molecule with minimal pre-activation can streamline syntheses and expand the opportunities to explore the utility of complex molecules in areas ranging from the pharmaceutical industry to materials science. Indeed, the issue of selectivity is paramount in the development of all C-H bond functionalization methods. Several groups have developed elegant approaches towards achieving selectivity in molecules that possess many sterically and electronically similar C-H bonds. Many of these approaches are discussed in detail in the accompanying articles in this special issue of Chemical Reviews. One approach that has seen widespread success involves the use of a proximal heteroatom that serves as a directing group for the selective functionalization of a specific C-H bond. In a survey of examples of heteroatom-directed Rh catalysis, two mechanistically distinct reaction pathways are revealed. In one case, the heteroatom acts as a chelator to bind the Rh catalyst, facilitating reactivity at a proximal site. In this case, the formation of a five-membered metallacycle provides a favorable driving force in inducing reactivity at the desired location. In the other case, the heteroatom initially coordinates the Rh catalyst and then acts to stabilize the formation of a metal-carbon bond at a proximal site. A true test of the utility of a synthetic method is in its application to the synthesis of natural products or complex molecules. Several groups have demonstrated the applicability of C-H bond functionalization reactions towards complex molecule synthesis. Target-oriented synthesis provides a platform to test the effectiveness of a method in unique chemical and steric environments. In this respect, Rh-catalyzed methods for C-H bond functionalization stand out, with several syntheses being described in the literature that utilize C-H bond functionalization in a key step. These syntheses are highlighted following the discussion of the method they employ.

This book was released on 2012 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently in the Ellman and Bergman groups a method was discovered for preparing 1,2-dihydropyridines via rhodium-catalyzed coupling of [alpha], [beta]-unsaturated imines and alkynes. Subsequent in situ oxidation provides access to the corresponding pyridines. This method was expanded to include terminal alkynes, challenging substrates for transition-metal mediated transformations. In contrast formal reduction of the dihydropyridine intermediates through Diels-Alder reaction with alkenes provides access to isoquinuclidines, an important class of piperidines, in excellent diastereoselectivities.
