Description

Description générale

TFFH is an in situ coupling reagents which smoothly converts protected amino acids to the corresponding acid fluoride in the presence of base ^[1]. Acid fluorides have proven are highly effective at coupling hindered amino acids such as α,α-disubstituted amino acids ^[2].
