(22S,23S)-22,23-Epoxysitosterol, (22R,23R)-22,23-epoxysitosterol, (22S, 23S)-22,23-epoxy-7-ketositosterol, (22R,23R)-22,23-epoxy-7-ketositosterol, (22S, 23S)-22,23-epoxy-7α-hydroxysitosterol, (22S,23S)-22,23-epoxy-7β-hydroxysitosterol, and (22R, 23R)-22,23-epoxy-7β-hydroxysitosterol were synthesized. Their 1H and 13C NMR and the mass spectra of their trimethylsilyl derivatives were studied.
