The present invention describes disorazoles and their analogues as described in formula III wherein the variables are defined in the description, or pharmaceutically acceptable salts thereof. Described is also a novel synthetic pathway for the production of disorazoles and their analogues, using two precursors twice in coupling reactions and a final cyclisation for a compound of formula III. The compounds of the present invention are useful as anti-cancer drugs.

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.

The invention relates to a process halogenation, which comprises halogenating a chemical compound in the presence of a halogenase, where the halogenase is
(a) encoded by the sequence specified in SEQ ID NO: 1 or a sequence derived therefrom on the basis of the degeneracy of the genetic code, or is
(b) encoded by a nucleic acid sequence which codes for a functional fragment of (a) or
(c) by a sequence which hybridizes with (a) or (b) under standard conditions, or is
(d) encoded by a sequence which has more than 30% identity or more than 60% similarity with the sequence specified under (a).
Diastereoselective Formation of 5-Vinylcyclopentenes from 1,6-Enynes: Cobalt-Mediated C−H Allylic Activation and Formal 5-Endo-Dig Cyclization

[GRAPHICS]A novel intramolecular cyclization reaction mediated by dicobalt octacarbonyl (Co-2(CO)(8)) is reported. Thermolysis in an argon atmosphere transforms the cobalt complex of 1-trimethyisilyl-6-hepten-1-ynes into 1-trimethylsilyl-5-vinylcyclopentenes in good yield and in a highly diastereoselective manner. This formal 5-endo-dig cyclization is proposed to proceed via an allylic C-H oxidative addition.
