Figure : Predictions for the Diels-Alder and Bischler-Napieralski reaction using 'Ring Breaker' and the standard model on compounds obtained from the literature employing commonly used ring formations. For each prediction, the patent id or Reaxys id corresponding to the template used has been given as a precedent. In all cases, the probability 'p(x)' of predicting the template for the given compound has been shown, where 'x' refers to the prediction's rank (i.e. 'p(1) = 0.983' means the first prediction with an associated probability of 0.983). In cases where the precursors have been highlighted in a box, the predicted disconnection matches that reported in the literature. The literature reference from which the compound was obtained is given for each example. We have refrained from exhaustively showing all possible disconnections and have chosen the first prediction that can be applied to generate a set of reactants, regardless of whether they reflect the 'ground truth', to show the raw predictions. Models trained on the USPTO and Reaxys datasets perform the same in all cases shown above with the exception of the Bischler-Napieralski reaction predicted for compound 9 using the USPTO dataset.
