Sulfoxide-Based Enantioselective Nazarov Cyclization: Divergent Syntheses of (+)-Isopaucifloral F, (+)-Quadrangularin A, and (+)-Pallidol. Chemistry (Weinheim an der Bergstrasse, Germany), 2016, Oct-04, Volume: 22, Issue:41 The synthesis of enantiomerically pure 3-aryl substituted indanones is developed using an enantioselective sulfoxide-based Knoevenagel condensation/Nazarov cyclization procedure. After the reductive desulfonation of the methyl para-tolyl sulfoxide-containing chiral auxiliary under mild conditions, selected enantiomerically pure indanone is used for the divergent total syntheses of three resveratrol natural products (+)-isopaucifloral F, (+)-quadrangularin A, and (+)-pallidol. Topics: Biological Products; Cyclization; Indans; Molecular Structure; Polycyclic Compounds; Stereoisomerism; Stilbenes; Sulfoxides	2016
A scalable biomimetic synthesis of resveratrol dimers and systematic evaluation of their antioxidant activities. Angewandte Chemie (International ed. in English), 2015, Mar-16, Volume: 54, Issue:12 An efficient synthetic route to the resveratrol oligomers quadrangularin A and pallidol is reported. It features a scalable biomimetic oxidative dimerization that proceeds in excellent yield and with complete regioselectivity. A systematic evaluation of the natural products and their synthetic precursors as radical-trapping antioxidants has revealed that, contrary to popular belief, this mode of action is unlikely to account for their observed biological activity. Topics: Antioxidants; Biological Products; Biomimetics; Cell Line; Dimerization; Humans; Indolequinones; Oxidation-Reduction; Polycyclic Compounds; Resveratrol; Stereoisomerism; Stilbenes	2015
