HBTU = 2-(1H-benzo-triazole-1-yl)-1,1,3,3-tetramethyluronium
HOBt = N-hydroxybenzotriazole
HOSu = H-Hydroxysuccinimide
BOP = Benzotriazolyl N-oxytrisdimethylaminophosphonium hexafluorophosphate
DCC = Dicylohexylcarbodiimide
Still have a question (shame on me)
There were two HBTU s. This one:
2-(1H-benzo-triazol-1-yl)-1,1,3,3-tetramethyluronium Hexafluorophosphate
And this one
O-(1H-benzotriazole-1-yl)-N,N,N,n-tetramethyluronium Hexafluorophosphate.
Are these the same?
