Paul Kilburn, director and Head of Medicinal Chemistry at Lundbeck said: "Enamine's REAL Database is allowing us to expedite our hit explosion programs at unmatched speed and synthesis success.
"With Enamine's support, not only is it possible for researchers to screen for new leads against their novel targets, but our technology will allow them to narrow them down faster."

Thus, for the synthesis of C-5-alkenyl derivatives of (R)-pipecolic acid, formylation of enamine 5 by Vilsmeier-Haack reaction under reflux conditions was performed to provide protected aldehyde 6 (Scheme 1).
Specifically, Enamine will create a compound library of kinases, which are related to cancer.
Steroidal-4-en-3-ones such as 4-cholesten-3-one were treated with ozone to obtain a keto acid, 3,5-seco-4-norcholestan-5-on-3-oic acid (I), subsequently treated with amines to obtain enamine lactams which were discovered to react with Grignard reagents at elevated temperatures to yield novel unsaturated 3-alkyl derivativatives.
These ketones were synthesized by condensing the morpholine enamine of the appropriate cycloalkanone with pyridine-1-oxide in the presence of benzoyl chloride (Fig.
- Ukrainian chemical company Enamine Ltd has agreed to expand its collaboration in early drug discovery with Swiss biopharmaceutical company Actelion Pharmaceuticals, the company said.
The vinylic proton in the enamine is easily observed as a single peak at 8.81 ppm; signals at higher field belonging to the protons H-4 and 1-OH at [delta] 8.16 and 7.63 ppm, respectively, are coupled.

Then, 5 mol% of Bronsted acid was added to the reaction mixture in order to improve yields by accelerating the enamine formation and protonation of the zwitterionic intermediate [26-28].
