  • A. Tsuji–Trost reactions chosen
    Tsuji–Trost reactions are palladium-catalyzed allylic substitution processes widely used in organic synthesis to form carbon–carbon and carbon–heteroatom bonds with high regio- and stereocontrol.
  • B. 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.
  • C. 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.
  • D. Stork enamine reaction
    The Stork enamine reaction is a key carbon–carbon bond-forming method in organic chemistry that uses enamines as nucleophiles to alkylate or acylate carbonyl compounds in a controlled, selective way.
  • E. 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.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
