The application of one-and two-dimensional nuclear magnetic resonance techniques to the structure elucidation of two saponins from Nothapodytes foetidu is reported. Detailed structural information about the sapogenin, protobassic acid, and the oligosaccharidic chains, including sugar sequence and po

✦ Synopsis
Some time ago, Leonard, Milligan, and Brown' tentatively assigned a boat-boat conformation (I bb ) to 5-oxocanone (l-oxacyclooctan-5-one)(I), a compound vfth a potential transannular interaction of the ether oxygen with the carbonyl group. However, recent work has shown that simple

## Abstract Complete sets of ^1^H chemical shifts and spin coupling constants of testosterone and 17α‐methyltestosterone were determined by analysis of the 600 MHz ^1^H NMR spectra. The spin coupling constants of the two compounds have similar values, but the substitution of a methyl group at the 1
## Abstract Established NMR criteria from ^1^H, ^13^C and 2D __J__‐resolved ^13^C NMR spectra, and also ^1^H{^1^H} NOE experiments, were used to determine the constitution and configuration in a series of substituted penta‐1,3‐dien‐5‐ols.
