Abstract
Further examination of the chemical constituents of Wikstroemia sikokiana FRANCH. et SAV. (Thymelaeaceae) afforded (+) -chamaejasmenin B (C-3/C-3″-biflavanone) and (-) -erythro-1, 5-diphenylpentane-1, 3-diol. The unsettled absolute configuration of the 1, 3-diol was established as 1 (S) and 3 (S) on the basis of a synthesis using chiral styrene oxide as a starting material.Keywords
