e coupling reaction between N-aryl glycine esters and acylated amines has been developed. The reaction proceeded effectively under an oxygen atmosphere without the use of peroxide agents. This simple protocol allows for the preparation of a series of newcompounds in a moderate to excellent yield via the CDC reaction of a wide range of N-aryl glycinederivatives with acylated amines, which are of great

The present invention relates to compounds Formula (I): as inhibitors of AKT activity, which are useful for the treatment of susceptible neoplasms and viral infections.
vinylboronates and α‐iminoamides are effectively catalyzed by the novel hydroxy–thiourea catalyst 1 (up to 86 % yield, 93 % ee; see scheme). This reaction can be applied not only to the synthesis of the unnatural amino acid monomers but also to peptide oligomers.
