Target entity: Diels–Alder reaction Context triple: [Otto Diels, coDiscovererOf, Diels–Alder reaction]
-
A.
Diels–Alder reaction
chosen
The Diels–Alder reaction is a fundamental organic chemistry cycloaddition that forms six-membered rings by combining a conjugated diene with a dienophile in a single, stereospecific step.
-
B.
Robinson annulation reaction
The Robinson annulation reaction is a classic organic chemistry transformation that forms six-membered rings by combining a Michael addition with an intramolecular aldol condensation, widely used in the synthesis of complex cyclic molecules and natural products.
-
C.
Eschenmoser–Claisen rearrangement
The Eschenmoser–Claisen rearrangement is a variant of the Claisen rearrangement in organic chemistry that converts allylic alcohols and amides into γ,δ-unsaturated carbonyl compounds via a [3,3]-sigmatropic rearrangement.
-
D.
Barton reaction
The Barton reaction is an organic photochemical transformation that converts nitrite esters into δ-nitroso alcohols via intramolecular hydrogen abstraction and radical rearrangement.
-
E.
Suzuki coupling
Suzuki coupling is a widely used palladium-catalyzed cross-coupling reaction that forms carbon–carbon bonds between organoboron compounds and organic halides, fundamental in organic synthesis and pharmaceutical chemistry.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
