Acylation of diamines using α‐aryl‐β‐keto esters occurs regioselectively at the less hindered amino group. The transacylation using N‐alkylamino alcohol resulted in chemoselective O‐acylation in the absence of metal catalyst. Protection of the amino group is not necessary. These reactions proceed efficiently because of the pseudo‐intramolecular process.

The present invention relates to tricyclic heterocycles. These heterocyclic compounds are useful as TEAD binders and/or inhibitors of YAP-TEAD and TAZ-TEAD protein-protein interaction or binding and for the prevention and/or treatment of several medical conditions including hyperproliferative disorders and diseases, in particular cancer.
The present invention provides compounds of Formula (I), which are prodrugs of trans-4-[(1R)-(6-[4-(difluoromethyl)pyridin-2-yl]amino}-4-methyl-2,3′-bipyridin-6′-yl)-1-hydroxyethyl]cyclohexanecarboxylic acid, a potent inhibitor of Syk. The compounds are useful in the treatment and prevention of diseases mediated by the enzyme, such as asthma, COPD, rheumatoid arthritis and cancer.
