## Abstract 2βAzetidinones which carry a proton each on Cβ3 and Cβ4 often pose a problem in the correct assignment of the resonances due to these protons; titanium tetrachloride has been shown to be an effective and reliable n.m.r. shift reagent to differentiate between these two protons on the bas
The ' ' C chemical shifts of triterpenoidal olefins and epoxides related to lanosterol are described and discussed. The epoxide function located in the central part of the tetracyclic steroidal skeleton allows the evaluation of epoxidation-induced shifts (EIS) for several carbons. The most character
A new method is proposed for the estimation of aromatic solvent-induced shifts(ASI.9) in carbon-13 NMR spectroscopy. The observed C-13 ASIS are shown to be useful for studing the structure elucidation.
