WebSep 15, 2024 · Following a recent trend [19], [21] to imitate a chemist’s approach to retrosynthesis in two stages: (1) disconnecting a molecule at a reaction center, and (2) converting synthons into reactants; RetroPrime relies on two Transformers to predict reaction center and synthons-to-reactants, respectively. WebGraphRetro [13] also adopts a similar framework and generates the reactants by attaching leaving groups to synthons. Dual model [9] proposes a general energy based model framework that integrates both sequence and graph based models, and performs consistent training over forward and backward prediction directions. 3.
