Planning your route

Plan strategies first, as an expert chemist would.

Try Selenium Target molecule
Strategy Steps Key Idea
Chiral Pool (Ester-first) 2 From D-phenylalanine via esterification then N-acetylation. Lowest racemization risk.
Asymmetric Hydrogenation 3 Azlactone synthesis, methanolysis, then Rh-catalyzed enantioselective hydrogenation.
Enzymatic Resolution 3 Acetylate racemic DL-Phe, resolve with Acylase I, then esterify.

The selected route resolves into concrete reactions:

Reaction: enamide to chiral amino acid
Optimization 2/3
Palladium

Now optimize the conditions

Pick a reaction and screen catalysts, ligands, bases, and solvents in a single plate. Palladium designs the layout so every well counts.

FAQ

Frequently asked questions.

What kinds of molecules can b12 handle?

We specialize in complex molecules that go beyond standard library synthesis, including multi-step targets, novel scaffolds, and compounds with challenging selectivity requirements.

How is b12 different from library synthesis providers?

Library synthesis services handle simple, well-known transformations. b12 combines AI-driven retrosynthesis planning with expert execution to tackle harder, multi-step routes that library providers cannot.

Can I use the platform without ordering synthesis services?

Yes. Selenium, Palladium, and Cobalt are all available as self-serve software tools at app.b12-labs.com. Use them for retrosynthesis planning, plate design, and lab automation whether or not you order synthesis.

How much does plate design and execution cost?

Plate design and execution starts at $8,000 USD without substrates. Full molecular synthesis is quoted per project based on complexity. Contact us for a detailed estimate.

Is coding required?

No. All three tools are designed so scientists can describe intent in natural language. The AI handles protocol generation, plate layout, and workflow structure.

How long does it take to get started?

You can start using the platform immediately at app.b12-labs.com. For synthesis services, typical turnaround depends on molecular complexity. We provide a timeline with your quote.
