Isariotins A–D, Alkaloids from the Insect Pathogenic Fungus <i>Isaria tenuipes</i> BCC 7831

Abstract

Isariotins A-D (1- 4), alkaloids possessing a unique bicyclo[3.3.1]nonane ring, were isolated from the insect pathogenic fungus Isaria tenuipes BCC 7831. The structures of these compounds were elucidated primarily by NMR and mass spectroscopic analyses.
