## Abstract The profisetinidins are the most important polyflavanoids of commerce, making up the major constituents of wattle and quebracho tannins. Even within the dimeric profisetinidins, substantial complexity exists because of stereo‐, regio‐, rotational and conformational isomers. Definition o

✦ Synopsis
It has been reported (2) that cis-2-methyl-1-acetylcyclohexane [a] exists largely (at least -89%) in the conformation Is (rather than 58% II+ 42% Ia, approximately, assuming additivity of A-values (2,3) and ignoring other considerations), and [b] it reacts faster (33:l) towards hydroxylamine than its isomer (IIIa, neglecting the diaxial conformation).

## Abstract The 100 MHz spectra of 2‐methyl‐, 4‐methyl‐, 4,5,8‐trimethyl‐ and 4,5,7‐trimethyl‐1‐tetralones have been analysed as 8‐spin systems using iterative computation. The monomethyl derivatives exist in inverting half‐chair conformations, the 2‐methyl group favouring the equatorial site and t
