for the preparation of N4-dialkyl-L-asparegine and N5-dialkyl-L-glutamine derivatives is described. The applicability of these derivatives in the preparation of related peptides is illustrated by the syntheses of N2 - carbobenzoxy - (N4 - dimethyl) - L - asparaginyl - (S - benzyl) - L - cysteinyl - L -prolyl - L - leucylglycine amide and N2- carbobenzoxy - (N5 - dimethyl) - L - gtutaminyl - L - asparaginyl
描述了制备N 4-二烷基-L-天冬酰胺和N 5-二烷基-L-谷氨酰胺衍生物的通用且方便的方法。这些衍生物在相关肽的制备中的适用性通过合成N 2-碳苯并-(N 4-二甲基)-L-天冬酰胺基-(S-苄基)-L-半胱氨酰基-L-脯氨酰基-L-亮氨酰甘氨酸来说明。酰胺和N 2-碳苯甲酰-(N 5-二甲基)-L-gtutaminyl-L-天冬酰胺基-(S-苄基)-L-半胱氨酸-L-脯氨酰基-L-亮氨酰甘氨酸酰胺,收率令人满意。
