Flexible molecules with defined shape. Part 5. Conformational analysis of 2,4,6,n-polymethylated alkane derivatives
Abstract
Poly-2,4,6,n-methylated undecene-(3–6) and pentadecene-derivatives(8–11) have been synthesized. In these compounds each backbone segment displays local bi-conformational behaviour. The effect of oxygen-substituents on the conformer population of the individual backbone segments has been studied by evaluating 3JH,H and 3JC,C coupling constants.
