The previous X-ray-crystallographic determination of the relative configuration of P-1894B, a potent prolyl hydroxylase inhibitor isolated from the culture broth of Streptomyces albogriseolus, was extended by means of chemical and spectral studies. The absolute configuration of P-1894B (1) was established from the absolute configuration of two constituent monosaccharides, L-aculose (3) and L-rhodinose (4), produced by chemical degradation of 1. The absolute configuration of the aglycone part (aquayamycin) was also established as 2. The stereostructure of the reduction product (11) obtained by the catalytic hydrogenation of 1 was also elucidated.
