Albizzia saman, a leguminous plant, is known to open its leaves in the daytime and sleep at night with the leaves folded. β-D-Glucopyranosyl 12-hydroxyjasmonate (1) was isolated as an endogenous chemical factor controlling this leafmovement. We developed a concise synthesis of optically pure (-)-1 in 9 steps from (+)-2 with a total yield of 58%. Similarly, such analogs of 1 as epi-LCF (13), enantiomer (14), and galactoside (19) were synthesized for a structure activity relationship (SAR) study. The results of this SAR study strongly suggest that the mechanism for the leaf-closing activity of 1 would be different from that of methyl jasmonate, and also suggest the involvement of a different kind of target protein which recognizes the trans-isomer of a jasmonate derivative.
