Am. courses that prepare you to earn It is applicable to the functionalization of primary amides, sulfonamides, and other N-functional groups that typically resist classical acylations and can be applied to late-stage functionalizations. These reactions are considered together because their chemistry is so similar. : a significant breakthrough for the construction of amides and peptide linkages.
