The present invention relates to novel pharmaceutically-useful compounds which are antagonists of the 5-oxo-ETE receptors, such as the OXE receptor. These compounds have use as therapeutic and/or prophylactic agents for diseases characterized by tissue eosinophilia, such as inflammatory conditions including respiratory diseases. The invention also relates to pharmaceutical compositions, to the use of such compounds and compositions as medicaments, and to therapeutic methods.
11-Chloro-3-methoxy-2-undecenal was synthesized from 8-bromooctanol, and an annelation reaction with this aldehyde and ethyl acetoacetate proceeded to give the ethyl 6-(8-chlorooctyl)salicylate. Ethyl 6-(8-chlorooctyl)salicylate was converted to ethyl 6-(7-formylheptyl)-2-methoxybenzoate through the iodide after protection of the phenolic hydroxyl group. Finally, the Wittig reaction with the aldehyde and triphenylphosphonium

This invention concerns a promoted catalyst system for making one or more alkanols from synthesis gas. The catalyst system contains a ruthenium compound and a halogen promoter dispersed in a low-melting tetraorganophosphonium salt. The halogen promoter is a compound capable of generating HX (where X═Cl, Br, or I) under reaction conditions. The invention also concerns a process for selectively preparing one or more alkanols from synthesis gas using the promoted catalyst system.

Batzelladine C (3) is a tricyclic guanidine alkaloid of unknown stereochemistry at one centre as well as unknown absolute stereochemistry. The two possible diastereoisomers of the methylester corresponding to this compound have been synthesised, permitting the relative and absolute stereochemistry of this compound to be assigned.
