Diels Alder Reaction

Abstract The reactions of 2-rm-butyl-3-methoxy-4-methyl-2,4-dihydropyrrolo[3,4-b]indole (3) with dialkyl acetylenedicarboxylates are decisively influenced by the solvent. In the presence of alcohols as protic and polar solvents Michael addition is prefered, while in aprotic and less polar solvents like ether the Diels-Alder reaction is favoured. Based on stereospecific hydrolysis and isotopic labeling dipolar intermediates are discussed. The results are of current interest for mechanistic and theoretical reasons

The Given

: Several easy, efficient and convenient procedures to access indoles fused heterocyclic systems are described in this review. These heterocyclic systems were synthesized from several cyclic or acyclic molecules via a variety of reactions such as Diels-Alder reaction, Michael addition, Morita-Baylis-Hillmann reaction and many other domino/Cascade approaches with high selectivity. Most of the given protocols in this review proceed though organocatalytic pathways, however some underwent via different catalytic and non-catalytic reactions.
