Streptolidine is an amino acid isolated from the hydrolyzate of the Streptomyces antibiotics streptothricin and streptolin.^[1] Its structure was first elucidated by chemical degradation^[2] and later by x-ray crystallography.^[3]

Synthesis

Syntheses have been accomplished from D-ribose^[4] and D-xylose.^[5]
