Abstract :
Oryzamutaic acids B–G (1–6), structurally unique nitrogen-containing heterocyclic alkaloids, were isolated from the endosperm (polished rice) of an Oryza sativa mutant. The structures and relative stereochemistries of 1–6 were elucidated on the basis of spectroscopic and single-crystal X-ray diffraction analyses.
