Asymmetric synthesis of a novel phenylogous amino acid mimicking an extended dipeptide
摘要:
Synthesis of an orthogonally protected form of phenylogous amino acid I which mimics an extended conformation of the dipeptide Arg-Gly was achieved. Key steps involve a diastereoselective addition of allylic organometallic reagents to chiral imine 2 and a palladium mediated carboalkoxylation of aryl bromide 5.
