Our Contributions to the Literature Regarding Computer-Assisted Structure Elucidation

When writing a publication how many of us conduct complete literature searches? For those of us who do not have access to Scifinder how are we finding our literature? Probably through Google Scholar? When I write a paper I admit that some of my searches may be less than complete but I do try and stay informed in regards to what is going on in my domain. VERY occasionally I get feedback from reviewers pointing me to references that they feel I either ignored or was unaware of. Many times they are co-authored by the reviewer themselves…and it is pretty easy to figure out who the reviewers are ūüôā

Today I received an email in my inbox about the latest article in the Journal of Cheminformatics.¬†It is¬†OMG: Open Molecule Generator. The article is¬†here.¬†¬†The abstract opens with “Computer Assisted Structure Elucidation has been used for decades to discover the chemical structure of unknown compounds. In this work we introduce the first open source structure generator, ¬†Open ¬†Molecule ¬†Generator ¬†(OMG), ¬†which ¬†for ¬†a ¬†given ¬†elemental ¬†composition produces ¬†all ¬†non-isomorphic ¬†chemical ¬†structures ¬†that ¬†match ¬†that ¬†elemental ¬†composition.”

Having been involved with Computer-Assisted Structure Elucidation for many years, having co-authored a book about it (here) and probably the definitive review article from the past 5 years (here) I would have assumed that our work would have been referenced. I was surprised to see that our work was not referenced while other CASE systems were. Articles we’ve issued over the past few years are below. I’ve gathered them here to point the authors to in case they want to reference any of them and missed them in the literatire search.

I am taking advantage of the fact that I can leave comments on the provisional manuscript¬†here¬†(what a great capability!!!) and will let them know about this list. it would be good to compare the performance of the OMG with the structure generator under ACD/Structure Elucidator sometime….
