CC1=NN2C(C)=CN=C2C=C1  is translated into 3,6-dimethylimidazo[1,2-a]pyridazine, which is not recognized by ChemDraw.





ChemDraw translates the same structure into 3,6-dimethylimidazo[1,2-b]pyridazine.





ChemDraw seems to be correct based on:

I am not familiar with IUPAC myself, so I cannot tell whether it's a bug or not.





Thanks.

Dear Yingyao,














Thank you for your report. At first sight it does indeed look like a naming bug on our side. I will look into it and let you know when it is fixed.

Hi, Dan





Do you have an estimation on when this will be fixed? We want to plan our next JChem upgrade. Thanks.

This issue has been fixed. The fix will be present in the 5.2.1 release, which should be available next week.





Thanks again for your precise report.
