Target entity: Overman rearrangement
Context triple: [Larry E. Overman, notableConcept, Overman rearrangement]
  • A. Overman rearrangement chosen
    The Overman rearrangement is an organic chemical reaction that converts allylic alcohol derivatives into allylic amines via a [3,3]-sigmatropic rearrangement of allylic trichloroacetimidates.
  • B. Stork–Danheiser rearrangement
    The Stork–Danheiser rearrangement is an organic reaction that transforms certain allylic alcohol derivatives into rearranged carbonyl compounds via a sigmatropic shift, widely used in complex molecule synthesis.
  • 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. 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.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
