HATU is commonly encountered in amine acylation reactions (i.e., amide formation). Such reactions are typically performed in two distinct reaction steps: (1) reaction of a carboxylic acid with HATU to form the OAt-active ester; then (2) addition of the nucleophile (amine) to the active ester solution to afford the acylated product. The reaction mechanism of carboxylic acid activation by HATU and subsequent N-acylation is s… WebHBTU/HATU/HCTU/TBTU Coupling. f. Fast Boc Deprotection with In Situ Coupling. g.
