Iridium-Catalyzed Intramolecular Asymmetric Allylic Etherification of Pyrimidinemethanols: Enantioselective Construction of Multifunctionalized Pyrimidine-Fused Oxazepines
An iridium-catalyzedintramolecularasymmetricallylic etherification of pyrimidinemethanols is described. In the presence of chiral-bridged biphenyl phosphoramidite ligand L3 and triethylborane, this process provided a class of novel pyrimidine-fused oxazepanes in up to 99% yield with 99.5% enantiomeric excess. The work addresses the challenge of insufficient nucleophilicity of aliphatic alcohols
A concise synthesis of spirofuranopyrimidines is described and relies on the addition of isopropyl 4-oxopiperidine-1-carboxylate to a pyrimidine dianion. The diol intermediate formed is subjected to cycloetherification conditions leading to an unprecedented heterocyclic template. (C) 2012 Elsevier Ltd. All rights reserved.

The design and synthesis of a second generation GPR119-agonist clinical candidate for the treatment of diabetes is described. Compound 16 (APD597, JNJ-38431055) was selected for preclinical development based on a good balance between agonist potency, intrinsic activity and in particular on its good solubility and reduced drug-drug interaction potential. In addition, extensive in vivo studies showed a more favorable metabolic profile that may avoid the generation of long lasting metabolites with the potential to accumulate in clinical studies.
