Calculate Digit Verification of CAS Registry Number 143673-80:
(8*1)+(7*4)+(6*3)+(5*6)+(4*7)+(3*3)+(2*8)+(1*0)=137
137 % 10 = 7

Synthesis of γ-benzyl tert-butoxycarbonyl-L-alanyl-D-glutamate and its derivatives

Zemlyakov

, p. 78 - 79 (1998)

A convenient method of obtaining Boc-L-Ala-D-iGln-OBzl and its amide analogs by condensing the N-hydroxysuccinimidyl ester of Boc-L-Ala with the γ-benzyl ester of D-Glu in the presence of NaHCO3, followed by amidation of the resulting Boc-L-Ala-D-Glu-γ-OBzl, is proposed. The use of l-adamantylamine and octadecylamine as amino components has enabled the corresponding α-adamantylamide and octadecylamide of the dipeptide to be obtained.
