Target entity: Stork–Danheiser rearrangement
Context triple: [Gilbert Stork, knownFor, Stork–Danheiser rearrangement]
  • A. 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.
  • B. 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.
  • C. 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.
  • D. 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.
  • E. Barton–McCombie deoxygenation
    Barton–McCombie deoxygenation is an organic chemistry reaction that converts alcohols into the corresponding hydrocarbons via radical-mediated removal of the hydroxyl group.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
