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).

-
A.
Sharpless asymmetric dihydroxylation
chosen
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.
-
B.
Sharpless epoxidation
Sharpless epoxidation is a landmark asymmetric oxidation reaction in organic chemistry that enables the enantioselective conversion of allylic alcohols to epoxides using chiral catalysts.
-
C.
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.
-
D.
Noyori asymmetric hydrogenation catalysts
Noyori asymmetric hydrogenation catalysts are highly efficient chiral ruthenium complexes that enable enantioselective hydrogenation of ketones and related substrates, revolutionizing asymmetric synthesis in organic chemistry.
-
E.
Evans auxiliary-based asymmetric synthesis
Evans auxiliary-based asymmetric synthesis is a widely influential chiral auxiliary strategy developed by David A. Evans that enables highly stereoselective construction of complex molecules in organic synthesis.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
