  Synthesis, SAR, and atropisomerism of imidazolopyrimidine DPP4 inhibitors

  摘要：

  The synthesis and SAR of aminomethyl-substituted imidazolopyrimidine DPP4 inhibitors bearing varied pendant aryl groups is described. Compound 1, which exists as a separable mixture of non-interconvertible atropisomers was used as the starting point for investigation. The effects of substituent pattern and type as well as stereochemical effects on inhibitor potency are discussed. (C) 2010 Elsevier Ltd. All rights reserved.
