A palladium-catalyzed γ-C(sp3)–H acetoxylation of triflyl-protected amines has been achieved. The use of pyridine or 2-alkoxyquinoline-type ligands is key to the success of this transformation. The reaction is highly diastereoselective and easily scalable, and constitutes a direct approach for the synthesis of γ-hydroxy-α-amino acids and β,γ-dihydroxy amines, which are not readily accessible by other routes.

A simple 1H and 13C NMR spectrometric analysis is demonstrated that permits differentiation of isoleucine and allo-isoleucine residues by inspection of the chemical shift and coupling constants of the signals associated with the proton and carbon at the α-stereocentre. This is applied to the estimation of epimerisation during metal-free N-arylation and peptide coupling reactions.

A macrocylic dodecapeptide, cycloforskamide, was isolated from the sea slug Pleurobranchus forskalii, collected off Ishigaki Island, Japan. Its planar structure was deduced by extensive NMR analyses and was further confirmed by MS/MS fragmentation analyses. Finally, the absolute configuration was determined by total hydrolysis and chiral-phase gas chromatographic analysis. This novel dodecapeptide contains three d-amino acids and three thiazoline heterocycles and exhibits cytotoxicity against murine leukemia P388 cells, with an IC 50 of 5.8 μM.
Highly tunable arylated cinchona alkaloids as bifunctional catalysts
Quigley, Cormac,Rodriguez-Docampo, Zaida,Connon, Stephen J.
supporting information; scheme or table, p. 1443 - 1445 (2012/03/11)
We report the design and evaluation of a library of chiral bifunctional organocatalysts in which the distance between the catalytically active units can be systematically varied.
