An ecient Michael addition of 4-hydroxycoumarins to α,β-unsaturated 2-acyl imidazoles catalyzed by Ni(OTf)2 as a Lewis acid has been developed. A series of 4-hydroxycoumarin derivatives were obtained in excellent yields (up to 96%) with a 2 mol% catalyst loading under mild conditions. ...
The cerium Ce(III), lanthanum La(III), and neodymium Nd(III) complexes with 4-hydroxy-3-(3-oxo-1-phenylbutyl)-2H-1-benzopyran-2-one (warfarin) (W) and 3, 3 ′ -benzylidenebis[4-hydroxycoumarin] (1) were synthesized and studied for the first time for cyto
A novel method for the synthesis of functionalized 3-substituted 4-hydroxycoumarins is reported. C-Acylation compounds were derived from the reaction of the N-hydroxybenzotriazole ester of the functionalized acetyl salicylic acids and a variety of active methylene compounds and cyclized to the ti...
