Hatu solubility
WebPeptide nucleic acid (PNA) is a totally artificial molecule that is used as a DNA analog in genetic engineering. PNA is just what its name indicates, consisting of a polypeptide backbone with nucleic acid bases attached as side chains. Note that the polypeptide backbone of PNA is not identical to that of natural proteins ( Fig. 5.18 ). 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 … See more HATU (1-[Bis(dimethylamino)methylene]-1H-1,2,3-triazolo[4,5-b]pyridinium 3-oxide hexafluorophosphate, Hexafluorophosphate Azabenzotriazole Tetramethyl Uronium) is a reagent used in peptide coupling chemistry … See more HATU was first reported by Louis A. Carpino in 1993 as an efficient means of preparing active esters derived from 1-hydroxy-7-azabenzotriazole See more
