Scaffold‐directed face selectivity Machine‐Learned from vectors of non‐covalent interactions

TLDR
In this article, a method to vectorize and machine-learn non-covalent interactions responsible for scaffold-directed reactions important in synthetic chemistry is described, and models trained on this representation predict correct face of approach in ca. 90% of Michael additions or Diels-Alder cycloadditions.
Abstract
This work describes a method to vectorize and Machine-Learn, ML, non-covalent interactions responsible for scaffold-directed reactions important in synthetic chemistry. Models trained on this representation predict correct face of approach in ca. 90 % of Michael additions or Diels-Alder cycloadditions. These accuracies are significantly higher than those based on traditional ML descriptors, energetic calculations, or intuition of experienced synthetic chemists. Our results also emphasize the importance of ML models being provided with relevant mechanistic knowledge; without such knowledge, these models cannot easily "transfer-learn" and extrapolate to previously unseen reaction mechanisms.

Planning chemical syntheses with deep neural networks and symbolic AI

TL;DR: This work combines Monte Carlo tree search with an expansion policy network that guides the search, and a filter network to pre-select the most promising retrosynthetic steps that solve for almost twice as many molecules, thirty times faster than the traditional computer-aided search method.

Molecular graph convolutions: moving beyond fingerprints

TL;DR: In this article, molecular graph convolutions, a machine learning architecture for learning from undirected graphs, specifically small molecules, are described. But they do not outperform all fingerprint-based methods, and they represent a new paradigm in ligand-based virtual screening with exciting opportunities for future improvement.
