## Abstract 2‐Azetidinones which carry a proton each on C‐3 and C‐4 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
## Abstract Earlier assignments of ^13^C NMR signals to C‐6 and C‐7 in 5,5‐dimethyl‐2‐norbornanone (1) based on lanthanide‐induced shifts are interchanged on the basis of studies of deuterium‐labeled derivatives of 1. The revised assignments are in accord with predictions based on substituent param
## Abstract The solution conformations of nine 3′,5′‐__O__‐(di‐__tert__‐butylsilanediyl) nucleosides, new sila analogues of cyclic nucleotides, were studied by proton NMR spectroscopy. The furanose rings of all the compounds studied are forced to take on the C‐3′‐__endo__ conformation by the 3′,5′‐
