Diels-Alder Reaction of Cyclopentadiene with Maleic Anhydride
Introduction In 1950, the chemists Otto Paul Hermann Diels, from Germany, and Kurt Alder, originally born in Prussia and then moved to Germany after World War I, received the Nobel Prize in chemistry for the discovery of a new way to synthesize cyclic molecules. Aptly titled the Diels-Alder Cycloaddition Reaction, this new mechanism allowed conjugated dienes to undergo addition reactions with a...
متن کاملThe Diels-Alder reaction of C60 and cyclopentadiene in mesoporous silica as a reaction medium.
As a new organic reaction medium, a periodic mesoporous inorganic material was found to function as a "solid solvent" in a Diels-Alder reaction of C(60) with cyclopentadiene. This finding was supported by a concentration effect and a kinetic study of the reaction.
متن کاملAsymmetric Brønsted acid-catalyzed aza-Diels–Alder reaction of cyclic C-acylimines with cyclopentadiene
A new chiral Brønsted acid-catalyzed aza-Diels-Alder reaction of cyclic C-acylimines with cyclopentadiene has been developed. The reaction provides optically active aza-tetracycles in good yields with high diastereo- and enantioselectivities under mild reaction conditions.
متن کاملExperimental and theoretical studies of Diels–Alder reaction between methyl (Z)-2-nitro-3-(4-nitrophenyl)-2-propenoate and cyclopentadiene
ABSTRACT The Diels-Alder reaction between methyl (Z)-2-nitro-3-(4-nitrophenyl)-2-propenoate and cyclopentadiene yields a mixture of carbodiene Diels-Alder adducts. B3LYP/6-31G(d) simulations indicate that the conversion of addends into methyl (1R*,2S*,3S*,4R*)-2-nitro-3-(4-nitrophenyl)-bicyclo[2.2.1]hept-5-ene-2-carboxylate occurs via two-stage heterodiene Diels-Alder reaction and (in a second ...
متن کاملEvidence for the concerted mechanism of the Diels-Alder reaction of butadiene with ethylene.
Diels-Alder reactions of substituted dienes and dienophiles have been found to cccur by both concerted and stepwise mechanisms.’.* The nature of the mechanism of the prototype Diels-Alder reaction of butadiene with ethylene to form cyclohexene is not only of fundamental interest but has generated fervid fulminations for favorite We wish to report new experimental evidence that is compatible onl...
