Objective

Predict the mechanism for 10 organic reactions drawn from the FlowER benchmark. Submit final product SMILES, mechanistic steps with electron push notations, and a methodology description. Concerted mechanisms (SN2, pericyclic, N-oxidation) have 1 step. Multi-step reactions (e.g., epoxide opening, Arbuzov) have 2+ steps. See reactions.json and example/worked_example.json in your workspace.

Reaction 2 is Diels-Alder [4+2] cycloaddition. Reaction 3 is Arbuzov (2-step: P attacks methyl iodide SN2, then I demethylates phosphonium). Reaction 4 is epoxide ring opening by amine (2-step: nucleophilic attack then proton transfer). Reaction 6 is hetero Diels-Alder with Danishefsky diene. Reactions 8,9 are N-oxidation of aromatic N by peracetic acid.",
