A reader has pointed out that this paper contains several cyclohexene and cyclohexa-1,4-diene structures that apparently contain trans double-bonds, e.g. structure 21. Our intention was to relate the structure of compounds along the synthetic route to that of the natural product target. The double-bonds are, of course, all cis, as shown in Scheme 2 of the paper, and we apologise for any confusion that our drawing structures in the form of 21 below has caused.
