In order to gain a deeper understanding of the stereochemical outcome of both the intermolecular and intramolecular Diels-Alder reactions detailed synthetic and computational investigations have been carried : Natalie A.

Miller. Diels–Alder (D–A) reaction is undoubtedly the most powerful [4 + 2] cycloaddition reaction in organic synthesis. It has been always considered as a model and a symbol of cycloaddition reactions. Intramolecular D–A reactions (IMDA) are also well recognized and can be employed in one or more steps for the total synth.

The intramolecular Diels–Alder reaction: recent advances and synthetic applications - Canadian Journal of Chemistry. Recent advances and examples of the intramolecular Diels–Alder reaction are summarized and applications to the total synthesis of natural products, both completed and Cited by: The Diels–Alder reaction is one of the most useful reactions available to the synthetic organic chemist.

It is thus surprising that the intramolecular version, in which both diene and dienophile are part of the same molecule, remained virtually unexplored for many by: Journals & Books; Help; COVID campus Reactive g-bonds Catalysts and high pressure Asymmetric Diels-Alder reactions Total synthesis Intramolecular Diels-Alder Reactions of Furans Scope and limitations ~O "Me 11 Synthetic applications of furan Diels-Alder chemistry 11 in a solution of silicon oil at Cited by: The intramolecular Diels-Alder furan (IMDAF) cycloaddition reaction is a versatile pericyclic reaction for the regio-and stereoselective synthesis of 6-membered carbocyclic and heterocyclic rings.
