The synthesis of a range of novel α-sulfenyl-β-chloroenones from the corresponding α-sulfenylketones, via a NCS mediated chlorination cascade, is described. The scope of the reaction has been investigated and compounds bearing alkyl- and arylthio substituents have been synthesised. In most instances, the Z α-sulfenyl-β-chloroenones were formed as the major products, while variation of the substituent

Indole and indole-related compounds, compositions and methods are disclosed. The compounds of the invention are useful as phospholipase inhibitors. The compounds and compositions of the invention are useful for treatment of phospholipase-related conditions, such as insulin-related, weight-related and/or cholesterol-related conditions in an animal subject.
Some α-haloketones react with furan in methanolic solution in the presence of base to form the 3-oxo-8-oxabicyclo[3.2.1]oct-6-enes (), the products derived from a [4+3] cycloaddition of an allylium intermediate ( or ).

The addition of hypochlorous acid to allenic hydrocarbons leads, in all cases, to the fixation of the Cl atom on the central carbon and to the fixation of the OH group on the more substituted carbon. The (α-chloroketones which might be produced by the inverse fixation are not obtained. The utilisation of Hückel's method explains these results theoretically and satisfactorily.
