Hi Willem, as we discussed I also submitted the R groups but than on the JAG-UCB scaffold.

Are there any plans to follow this up, it should be fruitful to explore the p5 pocket a bit more given the WaterMap + results of beta-lactam (TRY-UNI-2eddb1ff-7)?

Hi @bart.lenselink, thanks for reminding me of these. I’ll look into building blocks tomorrow, and see if we can get a couple made. Definitely interest on our side in exploring that pocket more

Perfect, in that case in the mean time Ill run a reaction based enumeration on that position.

Hi @bart.lenselink, I have already done that actually for Enamine building blocks with nucleophilic dispacement, Buchwald Hartwig, and Suzuki.

I’ll send them your way to save you some work!

Thanks! Ill submit them for docking first.
How about the following, reaction -where the beta-lactam can be varied by other halides?:

So here’s what we did:

This is one step from Enamine

So can either do direct nucleophilic displacement of halide (we looked for SMARTS of form [CX4H2][Br,I,$(OC(=O)C),$([O][S](=[O])(=[O])[C]([F])([F])[F]),$([O][S](=[O])(=[O])c1ccc(C)cc1)] in Enamine

Or for Suzuki and Buchwald-Hartwig, we first react OH -> OTf, and then form the C-N or C-C bond. In that case, we looked for boronic esters and primary amines available at Enamine.

Hopefully that captures pretty much everything you were imagining by varying the halide?
