Some reactions of 3,7-dimethyl-2,3-epoxyoctanal and its derivatives
The oxide of citral (3,7-dimethyl-2,3-epoxioctanal) readily enters into the Knoevenagel condensation with the formation of the corresponding epoxydienecarboxylic acid. The epoxidation and addition of dichlorocarbene to similar epoxydienes proceeds at the double bond which does not adjoin the epoxide ring. The condensation of the acetal of citral oxide with ketones with the formation of 1,3-dioxolanes proceeds with the participation of the epoxide ring.
