Exploiting π shielding interactions in a η6 arene-complexed chiral auxiliary
Jones, Graham B.,Guzel, Mustafa
, p. 4695 - 4699 (2000)
The origin of asymmetric induction in a chiral auxiliary derived from isomannide was probed using a series of η6 arene chromium carbonyl complexes. Diastereoselectivity as high as 99% was attainable, and subsequent spectroscopic analysis shed light on the role of π-π interactions. (C) 2000 Elsevier Science Ltd.

supporting information; scheme or table, p. 4900 - 4902 (2012/09/21)
A new class of monophosphine ligands has been prepared from natural chirality renewable source, 1,4:3,6-dianhydrohexitol compounds, via a nucleophilic substitution process, or a hydrophosphination reaction involving microwave activation. These ligands have been evaluated for the rhodium-catalyzed enantioselective hydrogenation of olefins giving good conversion and enantioselectivity up to 95% and 96% ee, respectively.

Abstract: Hepatitis C virus (HCV) is among the most important flaviviruses. It has a serine protease which is important for viral replication and this enzyme constitutes a suitable target for new anti-retroviral drugs. Herein we disclose a series of amide and ester peptide mimetic inhibitors of serine proteases, all of them obtained via coupling reactions of isomannide derivatives with N-protected amino acids. The arginine derivative 19 showed 45% of inhibition of NS3/4A serine protease at 100 μM and molecular modeling studies had shown that 19 interacted with the active site of this enzyme.

Exploiting π shielding interactions of η6 arene chromium (0) complexes: New auxiliaries derived from the biogenic chiral pool
Li, Jane,Xie, Longfei,Guzel, Mustafa,Heaton, Steven B.,Ma, Dong,Kallmerten, Amy E.,Jones, Graham B.
, p. 5459 - 5473 (2008/03/12)
A family of highly selective chiral auxiliaries containing arene chromium (0) complexes has been prepared using biogenic precursors from the chiral pool. The systems, derived from isomannide, prolinol, and xylofuranose were applied to the asymmetric Diels-Alder reaction of derived acrylate esters. Factors influencing stereoselectivity with the auxiliaries have been investigated and delineated including the impact of mixed ligands on the chromium (0) complex. Under optimal conditions, the auxiliaries give >95% e.e. and 98:2 exo:endo ratio in cycloaddition with cyclopentadiene.
