The new phytoecdysteroid 5α-ecdysterone 22-O-benzoate (I), C34H48O8, mp 262-274 deg C (methanol-water) D20+45.8 deg (methanol), has been isolated from the epigeal organ of Silene scarbiofolia Kom.The alkaline hydrolysis of (I) led to 5α-ecdysterone (II) and benzoic acid.The isomerization of ecdysterone (0.6percent KHCO3 in CH3OH) has yielded (II).Details of the IR, mass, and NMR spectra of compound (I) are given.

A flexible approach to ecdysteroids, chain elongated at C-26 and C-27, is reported. Key features are the addition of 5-lithio 2,3-dihydrofurans (3) to poststeron (10) and a stereoselective reduction of the 22-∞ group.
