Triple

Given a phrase, classify it is english named entity (e.g., persons, organizations, works of art) in Latin script, or not (e.g., literals, dates, URLs, verbose phrases). For disambiguation, the statement where the phrase occurs as object is also given. Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).

Phrase: Claisen-type rearrangement | Statement: [Eschenmoser–Claisen rearrangement, reactionClass, Claisen-type rearrangement]

Target entity: Claisen-type rearrangement
Context triple: [Eschenmoser–Claisen rearrangement, reactionClass, Claisen-type 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. 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. Arbuzov rearrangement
  The Arbuzov rearrangement is an organic reaction in which trialkyl or triaryl phosphites react with alkyl halides to form phosphonates, widely used in the synthesis of organophosphorus compounds.
• D. Ireland–Claisen rearrangement chosen
  The Ireland–Claisen rearrangement is a variant of the Claisen rearrangement in which an ester enolate undergoes a [3,3]-sigmatropic rearrangement to form γ,δ-unsaturated carboxylic acids with high stereocontrol.
• E. Overman rearrangement
  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.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target predicate: reactionClass
Context triple: [Eschenmoser–Claisen rearrangement, reactionClass, Claisen-type rearrangement]

• A. reactionType chosen
