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.
