4,5-seco-Probotryenols A–C, a new type of sesquiterpenoids from Stachybotrys bisbyi†
Abstract
4,5-seco-Probotryenols A–C (1–3), a new type of sesquiterpenoids named seco-probotryane-type sesquiterpenoid, have been obtained from Stachybotrys bisbyi (PYH05-7), along with five new botryane skeleton sesquiterpenoids (4, 5, and 8–10), and two known ones (6 and 7). Their structures were determined by NMR analyses, chemical derivatization, and X-ray crystallography.
