    Synthesis of naturally occurring 6-prenylcoumarins (1a, 2c and 3a) and their derivatives 1c, 1d, 1e, 2d and 3b–d starting from 2-prenyloxybenzaldehydes (8, 12 and 14) using tandem Claisen rearrangement and Wittig reaction is described. The coumarins 1a, 1e and 2c are converted to dihydropyranocoumarins (5a–e). The conversion of dihydroxanthyletin 5a and dihydroluvangetin 5d to the naturally occurring linear pyranocoumarins xanthyletin 6a and luvangetin 6b is also described.

    Bioassay-guided fractionation of the ethanolic extract of the roots of Toddalia asiatica led to the isolation of seven new prenylated coumarins (1–7) and 14 known analogues (8–21). The structures of 1–7 were elucidated by spectroscopic analysis, and their absolute configurations were determined by combined chemical methods and chiral separation analysis. Compounds 1–5, named toddalin A, 3‴-O-demethyltoddalin

    The absolute stereochemistries of (+)-toddalolactone (+)-1 and its related chiral coumarins [(+)-toddanol (+)-2, (+)-6-(2-hydroxy-3-methoxy-3-methylbutyl)-5,7-dimethoxycoumarin (+)-3, (+)-6-(3-chloro-2-hydroxy-3-methylbutyl)-5,7-dimethoxycoumarin (+)-4 and (-)-aculeatin (-)-5], isolated from Toddalia asiatica (L.) Lam. (T. aculeata Pers.), have been determined as R by ozonolysis of (+)-1 and by the chemical intercorrelation. Their optical purities were estimated by means of an H-1 NMR lanthanoid induced shift study using Eu(hfbc)3.
