摘要：

The structures of viridoxins A and B, two novel toxins isolated from the mycelial extract of the fungus Metarhizium flavoviride, were established by spectroscopic methods, chemical correlations, and a single-crystal X-ray analysis of viridoxin B. The absolute configuration of the viridoxins was determined by H-1 NMR analysis of chiral (R)- and (S)-O-methyl mandelate derivatives of viridoxin A.
