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: Synthesis of crown ethers | Statement: [Charles J. Pedersen, notableWork, Synthesis of crown ethers]

Target entity: Synthesis of crown ethers
Context triple: [Charles J. Pedersen, notableWork, Synthesis of crown ethers]

• A. 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.
• B. Mitsunobu macrolactonization
  Mitsunobu macrolactonization is a variant of the Mitsunobu reaction used in organic synthesis to form large-ring lactones by intramolecular esterification under mild, dehydrative conditions.
• C. The Logic of Chemical Synthesis
  The Logic of Chemical Synthesis is a seminal book by chemist Elias J. Corey that systematically presents the principles and strategies of retrosynthetic analysis for designing complex organic molecule syntheses.
• D. Yamaguchi macrolactonization
  Yamaguchi macrolactonization is a widely used organic synthesis method for forming large-ring lactones via intramolecular esterification activated by a mixed anhydride, particularly valuable in complex natural product synthesis.
• E. Enantioselective Chemical Synthesis
  Enantioselective Chemical Synthesis is a foundational work in organic chemistry that systematically presents strategies and methods for constructing chiral molecules with high stereocontrol.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Generate a one-sentence description of the target entity. 
You are given a context triple in the form (subject, predicate, object), where the object is the target entity.
