摘要:

AbstractBy conventional methods a mixture of diastereomeric 2,4, 6‐trimethylpimelic acids was prepared and separated by counter‐current distribution. The twomeso‐compounds were isolated in crystalline form, one of them (m.p. 130°) giving a dimethyl ester identical with a degradation product of the antibiotic borrelidin. The chirality (2‐R,4‐r,6‐S) of the acid of m.p. 130° was determined by an X‐ray structural analysis (see f
