Sažetak

After discovering that conjugated ketones may be converted to syn-epoxy-alcohols by DIBAH and oxygen, the investigation was expanded to cross-conjugated dienone systems, i. e. «-santonln and adrosta-1,4-diene-3,17-dione. The addition of 1 M DIBAH in toluene converted these dienones to intermediate aluminoxy derivatives which, after passing oxygen through the reaction mixture and continuous addition of DIBAH, gave the corresponding syn-epoxy-alcohols. No formation of diepoxy and anti-epoxy-alcohols was observed.
