Different Behaviouof of Disubtituted Aromatic Heterocycles in Polar Diels-Alder Reactions
Published: 30 November 2007 by MDPI in The 11th International Electronic Conference on Synthetic Organic Chemistry session General Organic Synthesis
Abstract: Dienophilic behaviour of disubstituted aromatic heterocycles towards normal electron demand Diels-Alder reactions is studied under thermal conditions. Formation of pyrrolyl-thiophenes are observed only in the reactions of nitrothiophenes with isoprene.
Keywords: heterocycles, Diels-Alder, dienophiles
