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).

Corey–Bakshi–Shibata reduction
The Corey–Bakshi–Shibata reduction is a widely used asymmetric organic reaction that enantioselectively reduces ketones to chiral alcohols using a chiral oxazaborolidine catalyst and borane.
-
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.
-
