C. Shin et al., DEHYDROOLIGOPEPTIDES .14. CONVENIENT COUPLING OF N-CARBOXY-ALPHA-DEHYDROAMINO ACID ANHYDRIDE WITH BOTH AMINE AND CARBOXYL COMPONENTS, Bulletin of the Chemical Society of Japan, 66(6), 1993, pp. 1844-1846
In order to further develop and expand the usefulness of N-carboxy-alp
ha-dehydroamino acid anhydride (DELTANCA), the optimum conditions of t
he acylation of DELTANCA with N-protected alpha-amino acids (AA) were
thoroughly examined. Furthermore, various kinds of AA or dipeptides as
a C-component were utilized in the acylation of DELTANCA, followed by
condensation with an AA methyl ester as an N-component.
