A review with 19 refs., starting from (-)-b-pinene (I), an efficient synthesis of qinghaosu (II) in natural form has been accomplished. The synthesis involves keto ester (III) as a key intermediate which is conveniently prepared using the Diels-Alder chem. developed in the authors' laboratory, i.e., reaction of ketone IV and isoprene in presence of Lewis acid.

Key words: ARTEANNUIN, DIELS-ALDER REACTION, BUTADIENE
