derivatives of methyl 2-amino-2-deoxy-alpha-D-glucopyranoside and amino acid or peptide esters are presented. The reaction of methyl 3,4,6-tri-O-acetyl-2-acetamido-2-deoxy-alpha-D-glucopyranoside and oxalyl chloride gave N-(methyl 3,4,6-tri-O-acetyl-2-deoxy-alpha-D-glucopyranosid-2-yl) oxamic acid chloride which on reaction with the ester of Gly, L-Ala, L-Phe, GlyGly, Gly-L-Phe and Gly-L-Ala afforded N-(methyl
介绍了甲基2-氨基-2-脱氧-α-D-吡喃葡萄糖苷和氨基酸或肽酯的新乙酰胺衍生物的合成。甲基3,4,6-三-O-乙酰基-2-乙酰氨基-2-脱氧-α-D-吡喃葡萄糖苷与草酰氯的反应得到N-(甲基3,4,6-三-O-乙酰基-2 -脱氧-α-D-吡喃葡萄糖苷-2-基)草酰胺酰氯,其与Gly,L-Ala,L-Phe,GlyGly,Gly-L-Phe和Gly-L-Ala的酯反应后得到N-( 3,4,6-三-O-乙酰基-2-脱氧-α-D-吡喃葡萄糖苷-2-基),N'-草酰氨基酸或二肽酯。使用溶液和固态的1H,13C NMR研究了草酰胺的结构。
