Chromones from the traditional Chinese medicine Saposhnikovia divaricata (Turcz.) Schischk exhibit various biological activities, among which the representative compounds, hamaudol and sec-O-glucosylhamaudol, have anti-allergic and anti-inflammatory activities. A concise asymmetric synthesis of hamaudol and sec-O-glucosylhamaudol has been accomplished. The key strategies included the Ca(OH)2-catalyzed regioselective construction of 6/6/6 tricyclic skeleton by aldol reaction/annulation of phenolic enolate with 3-methyl-2-butenal and the construction of chiral centers in the 3'-position by Jacobsen's asymmetric epoxidation reaction. This strategy provided a concise and rapid approach to synthesize hamaudol (linear 6-steps and 21% overall yield) and sec-O-glucosylhamaudol (linear 8-steps and 15% overall yield) from the commercial reagent.

Key words: Saposhnikovia Divaricata (Turcz.) schischk, chromone, hamaudol, sec-O-glucosylhamaudol, asymmetric synthesis
