, p. 1457 - 1464 (1992)
New amino acids, L-3-(2-carboxy-4-pyrrolyl)-alanine (1) and L-3-(2-oxo-5-pyridyl)-alanine (2), were isolated from Clitocybe acromelalga and their structures were deduced by spectral data and biogenesis and confirmed by syntheses. Stizolobic acid (5) was also found in this fungus.
