Notizen:
Oxidation of the 2-methoxyphenols 1c-f with phenyliodonium(III) diacetate (PIDA) in methanol resulted in the formation of the cyclohexa-2,4-dienones 4c-f, which dimerized spontaneously to a single product (5c-f) in each case. Using this method the synthesis of asatone (5a) and its demethoxy analogue (5b) was also accomplished starting from the readily available phenol derivatives 1a and 1b, respectively.
