Chemical structure of Fmoc-Asp(OtBu)-(Dmb)Gly-OH

GA21538

Fmoc-Asp(OtBu)-(Dmb)Gly-OH

Also known as 2-[(2,4-dimethoxyphenyl)methyl-[(2S)-2-(9H-fluoren-9-ylmethoxycarbonylamino)-4-[(2-methylpropan-2-yl)oxy]-4-oxobutanoyl]amino]acetic acid

Dmb backbone protection completely prevents base-catalyzed aspartimide formation of the Asp(OtBu)-Gly motif during Fmoc-SPPS· The Dmb moiety is readily introduced by coupling this Fmoc-dipeptide· Contrary to the Hmb derivative, cyclic lactones cannot be formed during activation
