Enantioselective Synthesis of Euonyminol
Journal of the American Chemical Society, 2021We describe an enantioselective total synthesis of the nonahydroxylated sesquiterpenoid euonyminol, the dihydro-β-agarofuran nucleus of the macrocyclic terpenoid alkaloids known as the cathedulins. Key features of the synthetic sequence include a highly diastereoselective intramolecular alkene oxyalkylation to establish the C10 quaternary center, an ...

The enantioselectivity of haloalkane dehalogenases
Tetrahedron Letters, 2001Two haloalkane dehalogenases were tested for their ability to perform kinetic resolutions of a series of racemic substrates and to convert meso substrates enantioselectively. For the kinetic resolutions E-values of up to 9 were measured and, in the conversions of the meso substrates, products were obtained with an enantiomeric excess of up to 47%.

Enantioselective Synthesis of Renieramide.
ChemInform, 2004A highly chemo- and enantioselective PTC alkylation has been developed that allows rapid access to orthogonally protected (S,S)-isodityrosine. Utility of this material in the construction of isodityrosine-containing cyclic peptides is demonstrated by synthesis of the natural product renieramide.

Enantioselective Sensing by Luminescence
2010Enantiomeric analysis is one of the crucial points for the sensor technology, due to the increasing importance that enantiomerically pure compounds and drugs have in pharmaceutic and agrochemical applications. Enantiomeric luminescent sensors give different responses by interaction or reaction with chiral molecules, allowing one to assess their optical

Enantioselective Synthesis of (+)-Peganumine A
Journal of the American Chemical Society, 2016A gram-scale enantioselective total synthesis of (+)-peganumine A was accomplished in 7 steps from commercially available 6-methoxytryptamine. Key steps included (a) a Liebeskind-Srogl cross-coupling; (b) a one-pot construction of the tetracyclic skeleton from an ω-isocyano-γ-oxo-aldehyde via a sequence of an unprecedented C-C bond forming ...
