Diels-Alder reaction-aromatization approach toward functionalized ring C allocolchicinoids. Enantioselective total synthesis of (-)-7S-allocolchicine.
Allocolchicinoids are analogues of the important antimitotic compound (-)-colchicine 1. A strategy is reported for the synthesis of ring C functionalized allocolchicinoids, which is based on aExpand

Three-component asymmetric catalytic Ugi reaction--concinnity from diversity by substrate-mediated catalyst assembly.
The first chiral catalyst for the three-component Ugi reaction was identified as a result of a screen of a large set of different BOROX catalysts. The BOROX catalysts were assembled in situ from aExpand

Origin of the regioselectivity in an intramolecular nucleophilic addition to arene chromium tricarbonyl complexes
The source of the regioselectivity in the intramolecular nucleophilic addition of nitrile-stabilized carbanions to arene chromium tricarbonyl complexes was investigated for seven differentExpand
