## Abstract Hydroxyiridals β monocyclic triterpenoids β are found abundantly in sword lilies. They feature a homofarnesyl side chain that is hydroxylated at one of the allylic methylene groups, which gives rise to a chiral carbon atom. The absolute configuration of six hydroxyiridals from different

After the conformation I was clarified to 5a,lOa-cis-solidagolactones by lH NMR measurement with Eu(dpm)3 and chemical transformations, the CD homoallylic benzoate chirality method was applied to the homoallylic alcohol system of solidagolactone IV (la) for a chiroptical determination of the absolut
Each of the chiral 1,2-and 1,3-diols examined was derivatized exclusively to a single diastereomeric acetal by the use of a new axially chiral reagent, 2%-methoxy-1,1%-binaphthalene-8-carbaldehyde (MBC). The absolute configuration of the original 1,2-and 1,3-diols was determined by the NOE correlati
Mosher's (IH) method to elucidate the absolute configuration of secondary alcohols was reexamined by use of high-field FT NMR spectroscopy, which enables assignment of most of the protons of complex molecules. There is a systematic arrangement of Ab (bs -8,) values obtained for the (R)-and (S)-MTPA
