The first synthesis of (±)-harzianopyridone, an antifungalmetabolite of Trichodermaharzianum, has been achieved by metalation of 6-substituted-2,3-dimethoxy-4-pyridyl-N,N-diisopropylcarbamates. Moreover, the chosen strategy allowed the preparation of harzianopyridone analogs, by varying the groups at C-4, C-5 and C-6 on the pyridine ring.

The problem addressed was that of providing novel polymers which are preparable with a low level of complexity, with the possibility of controlled influence on the physicochemical properties thereof within wide limits in the course of synthesis, and which are usable as active media in electrical charge storage elements for high storage capacity, long lifetime and stable charging/discharging plateaus.
9,10-Bis(1,3-dithiol-2-ylidene)-9,10-dihydroanthracene polymers consisting of an oligomeric or polymeric compound of the general formula I have been found.

A fused-ring quinone-substituted polynorbornene has recurring units of formula (1) and/or (2) below.
In formulas (1) and (2), A1 is independently a substituent of formula (3) or (4) below, n is an integer from 1 to 6, and A2 is a substituent of formula (5) or (6) below.
In formulas (3) to (6), each X is independently a single bond or a divalent group, and Ar1 and Ar2 are each independently an aromatic hydrocarbon ring or an oxygen atom or sulfur atom-containing aromatic heterocycle that forms together with two carbon atoms on a benzoquinone skeleton. This polymer has charge-storing properties and, when used as an electrode active material, is capable of providing a high-performance battery possessing high capacity, high rate characteristics and high cycle characteristics.
