described. These compounds are potent inhibitors of the 5-lipoxygenase from RBL-1 cells and also inhibitbovine seminal vesicle cyclooxygenase. Structure-activity relationships for these two enzymes are different, implying specific enzyme inhibition rather than a nonspecific antioxidant effect. 2-(Aryl-methyl)-1-naphthols are among the most potent 5-lipoxygenaseinhibitors reported (IC50 values generally
A streamlined method for the enantioselective synthesis of 2-amino-4H-chromenes from readily available 2-alkyl-substitutedphenols and active methylene compounds bearing a cyano group with up to 97% ee is presented. This reaction is a cascade procedure including manganese dioxide mediated C–H oxidation for the generation of o-quinone methides and bifunctional squaramide-catalyzed Michael addition/cyclization
