Development of an open-source software for isomer enumeration

open access: yesJournal of Cheminformatics, 2023
This article documents enu, a freely-downloadable, open-source and stand-alone program written in C++ for the enumeration of the constitutional isomers and stereoisomers of a molecular formula.

Chirality and stereoisomerism of organic multicomponent crystals in the CSD

open access: yes, 2020
With the current interest in multicomponent crystals containing chiral residues, a wide variety of studies could benefit from a comprehensive inventory of chirality in multicomponent crystals.

Stereoisomerism in pentaerythritol-bridged cyclotriphosphazene tri-spiranes: spiro and ansa 1,3-propanediyldioxy disubstituted derivatives [PDF]

open access: yes, 2005
Four isomeric products were isolated and purified from the reaction of 1,3-propanediol with the tetra-spirane cyclophosphazene-organophosphate compound (1): viz. the di-monospiro (2a), di-monoansa (2b) and two monospiro-monoansa derivatives (2c) and (2d).

Early contributions of crystallography to the atomic theory of matter

open access: yesSubstantia, 2019
After briefly presenting early hypotheses on the submicroscopic origin of symmetry and polyhedral morphology in the crystals, the structural model proposed by Haüy in 1784, based on the periodic repetition of integrant molecules made up of simple ...

Stereoisomerism and Structures of Rigid Cylindrical Cycloarylenes

open access: yesBulletin of the Chemical Society of Japan, 2018
Stereoisomerism is one of the most fundamental and indispensable notions in chemistry. We have recently found that a novel form of stereoisomerism emerges in cycloarylenes, cyclic arrays of aromatic panels.
