Abstract

Selective Synthesis of Cyano-Functionalized 2-Aryl-4H-chromenes and 2-Amino--4H-chromene-3-carbonitriles by Catalyst-Tuned Reactions of 2-Hydroxychalcones with 2-Substituted Acetonitriles. -Depending on the conditions, the reactions provide the title systems selectively. -(YIN*, G.; SHI, H.; XU, L.; WEI, X.; TAO, Q.; Synthesis 45 (2013) 3, 334-340, http://dx.doi.org/10.1055/s-0032-1317945 ; Dep.
