ChemAxon’s naming toolkit capabilities allow you to generate chemical structures from IUPAC, trivial, drug, CAS names and from CAS numbers.

Supported names include

  • IUPAC names, CAS names and generally systematic names
  • Common names (e.g. Toluene)
  • Drug names (e.g. Paracetamol, Doliprane)
  • Acronyms (e.g. ATP for "Adenosine Triphosphate")
  • CAS numbers (Note, this feature uses a Web service.)
  • For systematic names:
    • Chains
    • Monocycles
    • Retained/traditional names for ring systems with and without heteroatoms
    • Spiro ring systems
    • All cases of von Baeyer nomenclature for bridged ring systems
    • Fused ring systems
    • Ethers, esters, oximes, ...
    • Common characteristic groups
    • Ionic compounds
    • Compounds with one radical
    • Unlimited number of atoms and rings
    • All atom types
    • Substitutive and multiplicative nomenclatures
    • Stereochemistry

Current limitations

  • Molecules containing multiple radicals (e.g. ethane-1,2-diyl) are not supported yet.
  • Names containing isotopes are not supported yet.

Name to Structure Conversion in MarvinSketch

There are different ways how you can import a name directly into MarvinSketch and convert it to a chemical structure.

  • A simple method is to select the name in the text of any page and drag&drop or copy&paste it to MarvinSketch.

OR

  • Select the "Import Name" (Ctrl+Shift+N) option from the File menu, and write the name into the text field and click the "Import" button (Ctrl+I).

Name to Structure Conversion in MarvinView

Open a text file (.name) containing IUPAC names (one per row). MarvinView will open all the structures. Opening the same file in MarvinSketch, the program will ask you to select one structure (by its index number).

Name to structure conversion from command line

As a commandline tool, you can use  MolConverter  for name to structure conversion. Examples:

  1. Converting "test.name" name file to MOL file:
    molconvert mol test.name -o test.mol
  2. Converting "test.name" name file to "test.smi" SMILES file which also contains the name of the structures:
    molconvert smiles:n test.name>test.smi

The behavior of name to structure can be controlled using format options .

Marvin can also convert structures to names.
