Synthesis of optically active olivil type of lignan from L-arabinose using threo-selective aldol condensation as a key reaction.

Article abstract of DOI:10.1271/bbb.64.2320

The threo-selective aldol condensation of (3R, 4S)-3-hydroxy-5-trityloxy-4-pentanolide, which was prepared from L-arabinose, with piperonal was applied to the stereoselective synthesis of the olivil type of lignan, (2R, 3R, 4R)-4-benzyl-4-hydroxy-3-hydroxymethyl-2-(3,4-methylenedioxyphenyl)tetrahydrofuran.
