I first heard the term "para stereochemistry" from Salome Rieder (a PhD student at the ETH Zurich), who pointed me to this paper as a source for term: https://pubs.acs.org/doi/pdf/10.1021/ci00016a003
I tend to call this "dependent stereochemistry" since I think it's clear, but that's definitely something I just made up. :-) -greg On Wed, May 26, 2021 at 10:54 PM Jean-Marc Nuzillard < jm.nuzill...@univ-reims.fr> wrote: > Dear Paolo, > > According to https://goldbook.iupac.org/terms/view/P04921 > your interpretation is certainly the correct one. > I still have to find how this r/s assignment is determined. > > Many thanks again, > > Jean-Marc > > > Le 26/05/2021 à 22:40, Paolo Tosco a écrit : > > Dear Jean-Marc, > > > > I believe it indicates what the IUPAC Gold Book refers to as > pseudoasymmetry. > > Let’s see if others agree with my interpretation. > > > > Cheers, > > P. > > > >> On 26 May 2021, at 22:28, Jean-Marc Nuzillard < > jm.nuzill...@univ-reims.fr> wrote: > >> > >> I believed I sent a message with the same title a few minutes ago, but > apparently something went wrong. > >> > >> Reading the RDKit book about function FindMolChiralCenters(), > >> I saw that it provides a better handling of para-stereochemisry. > >> This concept is not familiar to me. > >> Google did not help and sent me back to the RDKit Book. > >> So, what is para-stereochemistry? > >> > >> Best regards, > >> > >> Jean-Marc > >> > >> -- > >> Jean-Marc Nuzillard > >> Directeur de Recherches au CNRS > >> > >> Institut de Chimie Moléculaire de Reims > >> CNRS UMR 7312 > >> Moulin de la Housse > >> CPCBAI, Bâtiment 18 > >> BP 1039 > >> 51687 REIMS Cedex 2 > >> France > >> > >> Tel : 03 26 91 82 10 > >> Fax : 03 26 91 31 66 > >> http://www.univ-reims.fr/icmr > >> http://eos.univ-reims.fr/LSD/CSNteam.html > >> > >> http://www.univ-reims.fr/LSD/ > >> http://www.univ-reims.fr/LSD/JmnSoft/ > >> > >> > >> > >> _______________________________________________ > >> Rdkit-discuss mailing list > >> Rdkit-discuss@lists.sourceforge.net > >> https://lists.sourceforge.net/lists/listinfo/rdkit-discuss > > > -- > Jean-Marc Nuzillard > Directeur de Recherches au CNRS > > Institut de Chimie Moléculaire de Reims > CNRS UMR 7312 > Moulin de la Housse > CPCBAI, Bâtiment 18 > BP 1039 > 51687 REIMS Cedex 2 > France > > Tel : 03 26 91 82 10 > Fax : 03 26 91 31 66 > http://www.univ-reims.fr/icmr > http://eos.univ-reims.fr/LSD/CSNteam.html > > http://www.univ-reims.fr/LSD/ > http://www.univ-reims.fr/LSD/JmnSoft/ > > > > _______________________________________________ > Rdkit-discuss mailing list > Rdkit-discuss@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/rdkit-discuss >
