2(2-acetamido-2-deoxy-3-O-D-glucopyranosyl)-alkanyl-pe-ptide I (R=methyl; R1=OH; R2=H, functional groups, C22-acyl; R4=OH; R6=OH, oxisuccinyl; R7=C1 C10 alkyl; X=L-alanyl, L-se-ryl, L-glycyl) was prepd. as immune adjuvant. Thus, t-butyl-oxycarbonyl-D-gln-methyl ester was dessolved in 60mL methanol and added to and ether soln. of CH2N2 at 0C Excess diazomethane was removed by addition of glacial acetic acid, and resulting mixture was concentrated and dried. As a resuly, Nacetyl-muramyl-L-Ala-D-Gin. methyl ester was obtained.
