Abstraet Potassiut~ lespedezate (1) is the leaf-opening substance of a nyetinastic plant, Lespedeza cuneata G. Don. We have synthesized two sugar-derivatives of 1, potassium galactolespedezate (4) and mannolespedezate (6). Both 4 and 6 were quite effective for the leaf-opening of Cass/a. raimosoides
In a previous paper, the syntheses of potassium galactolespedezate (1) and potassium galactoisolespedezate (2), artificial leaf-opening substances useful for bioorganic studies of nyctinasty were reported. The fluorescent probe compounds, fluorescence-labeled galactoisolespedezates (3, 10, 13), desi
