Abstract

New ergostane type ecdysteroids from the mushroom species Paxillus atrotomentosus: paxillosterone, its 20,22-p-hydroxybenzylidene acetal, atrotosterones A, B and C and 25-hydroxyatrotosterones A and B have been characterized. 20-Hydroxyecdysone asa minor constituent has also been isolated. Configuration at C(24) of paxillosterone was derived from proton 2D-ROESY NMR spectra of its cyclic phenylboronate derivatives. Configuration at C(24) of 25-hydroxyatrotosterone A was assigned by comparison of its NMR spectra with the spectra of both 24-epimers of makisterone A. (C) 1998 Elsevier Science Ltd.
