Hetero atoms withing a ring structure at multiple points

Hello CXN team,

Could someone help me in drawing a markush like this. A pyridine ring with 'Nitrogen' at both position 1 and 2. Please find the structure file attached. I tried with "position variation" bond, but 'N' gets attached to benzene with a carbon bond instead of being within the ring. I look forward to the support.

Thanks in advance.

Thanks & regards,

Yogitha

Hi Yogitha,

Do you want a structure where both the 1st and 2nd atoms can be carbon or nitrogen independently?

(N-N and C-C) also accepted. In this case modified_pyridine.mrv contains the right structure.

If you want to include only the cases where only one is Nitrogen and the other is carbon, then modified_pyridine2.mrv is a good solution. In this the two atoms need to be defined by an rgroup.

 

Bye,

Robert

Hi,

 

Yesterday I attached the file in the development mrv version. Now I attach it in mol, so you can watch it with the current version.

Hi Robert,

Thanks for the answer. But I want 'N' to be attached at both position 1 & 2. For this is that I have to draw a seperate Markush. One with 'N' at position 1 and the other with 'N' at position 2?

Thanks once again for the support.

Hi Yogitha,

 

The second example I've sent (modified_pyridine2.mol) is a markush where either one or the other position has an N atom. If you would like to include the case where both are nitrogens, the you can extend the R-group with a third definition having N at both positions.

Bye,

Robert
