Here we solve a long-standing challenge of the site-selective modification of secondary amides and present a simple two-step, metal-free approach to selectively modify a particular secondary amide in molecules containing multiple primary and secondary amides. Density functional theory (DFT) provides insight into the activation of C-N bonds. This study encompasses distinct chemical advances for late-stage modification of peptides thus harnessing the amides for the incorporation of various functional groups into natural and synthetic molecules.
A NEW CHIRAL RECOGNITION IN AMINOLYSIS OF 3-ACYL-4(R)-METHOXYCARBONYL-1,3-THIAZOLIDINE-2-THIONE WITH RACEMIC AMINES

A chiral recognition was observed in aminolysis of 3-acyl-4(R)-methoxycarbonyl-1,3-thiazolidine-2-thione 1 by racemic amine 2 to give an optically active amide (S-excess) and amine (R-excess).
