An abbreviated mechanistic description for DCC-mediated amide bond formation is illustrated as Path A. An alternative pathway for this process has been proposed as well, illustrated in Path B. In this alternative pathway, a second molecule of acid 1 out-competes the amine 4 for the pivotal activated acyl derivative 3, leading to a transient symmetrical anhydride 7(with discharge of 6). In Path B, anhydride 7 then is the active electrophile that reacts with amine 4 to give the observed amide...
OCHEM CHAPTER 26 A clever new method of peptide synthesis involving formation of amide bond by reaction of an alpha-keto acid with an n-alkylhydroxylamine, The reaction is thought to occur by nucleophilic addition of N-alkylhydroxylamine to the keto acid as if forming an imine followed by decarboxylation and elimination of water. Show the mechanism. Please show the mechanisms, and I WILL RATE 1 OH DMF R + N R + -R2 + H CO2 H20 20 ZI OH
