Amino acids are fundamental building blocks, which have been extensively used in drug design and organic synthesis. However, nonnatural amino acids are relatively less studied. In this work, the authors report the first HFIP-promoted de novo synthesis of nonnatural α-arylated amino esters and dipeptide mimetics (27 examples, up to 99 % yield) from readily available amines, ethyl glyoxylate and electron-rich

An efficient method for the synthesis of indolylglycine derivatives is described. The oxidativecoupling reactions of ethyl 2-(disubstituted amino)acetates with indoles proceeded smoothly in the presence of meta-chloroperoxybenzoic acid (mCPBA) under ambient conditions to produce indolylglycine derivatives in satisfactory to excellent yields.
