Target entity: Djerassi–Roche reaction Context triple: [Carl Djerassi, notableWork, Djerassi–Roche reaction]
-
A.
Chichibabin reaction
The Chichibabin reaction is an organic chemistry transformation that introduces an amino group into heteroaromatic compounds, especially pyridines, using sodium amide.
-
B.
Heck reaction
The Heck reaction is a palladium-catalyzed cross-coupling between alkenes and aryl or vinyl halides, widely used in organic synthesis to form carbon–carbon bonds.
-
C.
Ullmann reaction
The Ullmann reaction is a classic copper-catalyzed cross-coupling process that forms carbon–heteroatom or carbon–carbon bonds, historically important in aryl ether and amine synthesis.
-
D.
Eschenmoser sulfide contraction
Eschenmoser sulfide contraction is an organic rearrangement reaction that converts certain sulfur-containing intermediates into carbonyl compounds, widely used in complex molecule and natural product synthesis.
-
E.
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.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
