    • 2bc The reaction of 8 and methanol in the presence of acid catalyst (p-TsOH) afforded the methylated derivative 9 in 71% yield, Conversely, the conversion of 9 into 8 could be carried out in the presence of water and acid catalyst (conc. HCl) in 59% yield (Scheme 3). From the experiment we could propose the structure of 4a-c and 6a as described tentatively.
