Auxofuran, a Novel Metabolite That Stimulates the Growth of Fly Agaric, Is Produced by the Mycorrhiza Helper Bacterium Streptomyces Strain AcH 505
Characterization of these compounds provides the foundation for molecular analysis of the fungus-bacterium interaction in the ectomycorrhizal symbiosis between fly agaric and spruce.
Amides as Weak Coordinating Groups in Proximal C–H Bond Activation
Site selectivity is an inherent challenge in C–H functionalization reactions. The most intensively sought-after approaches have involved the employment of Lewis-basic coordinating groups to direct a
Palladium(II)-Catalyzed, Heteroatom-Directed, Regioselective C-H Nitration of Anilines Using Pyrimidine as a Removable Directing Group.
A new palladium-catalyzed, heteroatom-directed strategy for C-H nitration of anilines is described, using pyrimidine as the removable directing group and results in very good yields.

A palladium-catalyzed, ortho-selective C-H halogenation methodology is reported, which results in good yields of the halogenated products with excellent regioselectivity and interesting aspects with respect to the pathway of the reaction and the directing group abilities.
Palladium-Catalyzed Aerobic Oxidative Coupling of Allylic Alcohols with Anilines in the Synthesis of Nitrogen Heterocycles.
An unprecedented and expedient Pd-catalyzed oxidative coupling of allyl alcohols with anilines to afford β-amino ketones which are converted into substituted quinolines in a one-pot fashion, dispensing the need for unstable and costly enones.
Ruthenium-Catalyzed, Site-Selective C-H Allylation of Indoles with Allyl Alcohols as Coupling Partners.
A new ruthenium-catalyzed, heteroatom-directed strategy for C-H allylation of indoles that provides access to C2-allylated indoles by utilizing a strategy that does not require prefunctionalization of either of the coupling partners.
Ruthenium-catalyzed heteroatom-directed regioselective C-H arylation of indoles using a removable tether.
A new approach to C-2 arylated indoles has been developed by utilizing a ruthenium-catalyzed, heteroatom-directed regioselective C-H arylation that uses a removable directing group and compatibility of the catalytic system with halogen functional groups in the substrates.
Catalyst Control in Positional-Selective C-H Alkenylation of Isoxazoles and a Ruthenium-Mediated Assembly of Trisubstituted Pyrroles.
Synthetic elaboration of this C-H alkenylation product via ruthenium and copper co-catalysis leads to an efficient method for the assembly of densely substituted pyrroles.
Cobalt-Catalyzed C-H Nitration of Indoles by Employing a Removable Directing Group.
This approach provides a unique methodology involving a site-selective C-N bond formation for preparation of C-2 substituted nitro indoles, and utilization of the tBoc as the removable directing group enhances the synthetic utility of the method.
