Acutumine acetate (I) is reduced to II with an excess of lithium aluminium hydride in ether followed by decomposition of aluminium complex with ammonium chloride and water. It is well known that vinylogous esters of six membered rings are reduced to α, β-unsaturated ketones with lithium aluminium hydride. Our experimentals showed that a vinylogous ester (XIII) of five membered rings is reduced to an allyl alcohol (XIV) in quantitative yield under the conditions described in the reduction of I.
