Electrophilic Amination: New Synthetic Applications

Electrophilic aminating reagents can transfer N-protected group to carbanions or amines. N-Boc and N-Alloc protected amines or hydrazines were easily obtained using metalated t-butyl- or allyl-N-arylsulfonyloxycarbamate. N,O-Bis(trimethylsilyl) hydroxylamine or N-protected oxaziridines were reported to be convenient reagents to give N-protected derivatives.
