NER Named-entity recognition gpt-5-mini
Instruction
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).

Target entity: Breslow intermediate in organocatalysis
Context triple: [Ronald Breslow, knownFor, Breslow intermediate in organocatalysis]
  • A. 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.
  • B. Corey–Winter olefin synthesis
    Corey–Winter olefin synthesis is an organic reaction that converts 1,2-diols into alkenes via cyclic thiocarbonate intermediates, widely used for stereospecific formation of double bonds.
  • C. Corey–Nicolaou macrolactonization
    Corey–Nicolaou macrolactonization is a widely used organic synthesis reaction that forms large-ring lactones from hydroxy acids via an activated ester intermediate.
  • D. Sharpless asymmetric dihydroxylation
    Sharpless asymmetric dihydroxylation is a landmark chemical reaction that uses chiral catalysts to add two hydroxyl groups across an alkene with high enantioselectivity, revolutionizing asymmetric synthesis in organic chemistry.
  • E. Trost asymmetric allylic alkylation
    Trost asymmetric allylic alkylation is a palladium-catalyzed enantioselective carbon–carbon bond-forming reaction that enables the synthesis of chiral molecules from prochiral allylic substrates.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
