- MURGANTIOL AS A STINK BUG SYNERGISTIC ATTRACTANT FOR USE OUTDOORS
-
Provided herein are uses of the Harlequin bug pheromone, murgantiol, alone or in a synergistic combination with at least one other stink bug attractant, such as methyl (2E,4E,6Z)-decatrienoate or methyl (2E,4Z)-decadienoate, or both, for attracting stink bugs such as the brown marmorated stink bug in outdoor settings. Stink bug traps comprising murgantiol, or synergistic compositions comprising murgantiol with at least one other stink bug attractant, and methods of using these compositions in traps outdoors are provided. Compositions comprising murgantiol are also described as synergistic combinations of murgantiol with at least one other stink bug attractant.

- Readily accessible oxazolidine nitroxyl radicals: Bifunctional cocatalysts for simplified copper based aerobic oxidation
-
Using a two-step procedure a range of bifunctional oxazolidine nitroxyl radicals have been prepared. The application of these co-catalysts to the copper-based aerobic oxidation of alcohols was then investigated. From these studies it was found that the parent tetramethyloxazolidine nitroxyl radical L1 was competent for oxidation in the presence of 2,2′-bipyridine, and the bifunctional pyridyl-containing nitroxyl radicals L2 and L3 could be used in the absence of additional coordinating ligands. Following optimization, the scope of this simplified transformation was explored, demonstrating that a range of primary and secondary benzylic alcohols are readily oxidized. In addition, the oxidation of allylic alcohols and hydroquinone can be achieved. Copyright

- Highly stereoselective peptide modifications through Pd-catalyzed allylic alkylations of chelated peptide enolates
-
Deprotonation of peptides in the presence of zinc chloride gives rise to highly reactive nucleophiles that can be subjected to palladium-catalyzed allylic alkylation reactions. Excellent diastereoselectivities are obtained that are nearly independent of the allylic substrate used. By using this protocol, highly functionalized side chains can also be incorporated in excellent yields and selectivities. The stereochemicaloutcome of the reaction is exclusively controlled by the peptide chain as long as terminal π-allyl-palladium complexes are involved. Probably, there is a threefold coordination, at least, ofthe deprotonated peptide chain to the chelating zinc ion. In such metal peptide complexes, one face of the generated enolate is shielded by the side chain of the adjacent amino acid, thus directing the electrophilic attack onto the opposite face. This behavior explains why an S amino acid always generates an R amino acid (and the other way round).
