Synthesis of Terpineol from Alpha-Pinene Catalyzed by α-Hydroxy Acids
Molecules, 2022 We report the use of five alpha-hydroxy acids (citric, tartaric, mandelic, lactic and glycolic acids) as catalysts in the synthesis of terpineol from alpha-pinene.

Note of the hyper-Wiener index [PDF]
Journal of the Serbian Chemical Society, 2003 The hyper-Wiener index WW of a chemical tree T is defined as the sum of the products n1n2, over all pairs υ,ν of vertices of T, where n1 and n2 are the number of vertices of T, lying on the two sides of the path which connects υ and ν.

A generative model for molecule generation based on chemical reaction trees [PDF]
Journal of Chemical Physics, 2021 To develop useful drugs and materials, chemists synthesize diverse molecules by trying various reactants and reaction routes. Toward automating this process, we propose a deep generative model, called cascaded variational autoencoder (casVAE), for ...

Generation, Ranking and Unranking of Ordered Trees with Degree Bounds [PDF]
Electronic Proceedings in Theoretical Computer Science, 2016 We study the problem of generating, ranking and unranking of unlabeled ordered trees whose nodes have maximum degree of Δ. This class of trees represents a generalization of chemical trees. A chemical tree is an unlabeled tree in which no node has degree
