This paper describes a new, simple, general and efficient one-pot synthesis of mikanecic acid derivatives from allylic phosphonates, ethyl chloroformate and aqueous formaldehyde. The overall process involves a cascade sequence linking together metallation-alkoxycarbonylation, Horner-Wadworth-Emmons and Diels-Alder reactions.
