Abstract

cis-p-Coumaroylagmatine (1) was isolated from Albizzia julibrissin Durazz as a bioactive substance for nyctinasty. The compound was quite effective for leaf-opening of the plant at 1 × 10−5 M at night. Nyctinastic movement of Albizzia julibrissin Durazz is assumed to be controlled by the balance of concentration between 1 and an unknown leaf-closing substance.

    In addition, the leaves also close at night and open again in daylight [311]. This dynamic movement is controlled by bioactive chemical substances that differ based on the type of plant species [306–310,312–315]. Apart from touch sensitive Mimosa leaves, sunflowers also demonstrate multiple functions of photosensing, actuation (tracking the sun), and photosynthesis [174].

    Optically pure aglycons, (+)-18 and (−)-18, were prepared from commercially available (±)-methyl jasmonate ((±)-7) (Scheme 1). Optical resolution of racemic 7 was carried out according to the method by Kiyota.11 Racemic 7 was reduced by using NaBH4–CeCl3,15 and then one of the resulting diastereomers (8) was acetylated by Lipase PS with vinyl acetate to give unnatural-type acetate 10 and natural-type alcohol 11.
