Epoxide formation by sulphur y1id insertion into aldehydes under heterogeneous conditions in the presence of small quantities of water is described. Trimethylsulphonium and S-methylthiolanium bromide and iodide have been studied. For all alkyl substituents the bromide gives better results than the iodide, this is interpreted in terms of the reaction mechanism. Under optimum conditions high yields of

Inhibition of class IIa histonedeacetylase (HDAC) enzymes have been suggested as a therapeutic strategy for a number of diseases, including Huntington’sdisease. Catalytic-site small molecule inhibitors of the class IIa HDAC4, -5, -7, and -9 were developed. These trisubstituted diarylcyclopropanehydroxamic acids were designed to exploit a lower pocket that is characteristic for the class IIa HDACs

The diastereoselectivesynthesis of various substituted morpholines has been achieved from vinyloxiranes and amino-alcohols under sequential Pd(0)-catalyzed Tsuji–Trost/Fe(III)-catalyzed heterocyclization. Using the same strategy, 2,6-, 2,5-, and 2,3-disubstituted as well as 2,5,6- and 2,3,5-trisubstituted morpholines were obtained in good to excellent yields and diastereoselectivities.
Visible light-mediated radical alkenylation of benzylsulfonium salts was achieved by means of fac-Ir(ppy)3 as a photocatalyst, giving allylbenzenes as products. A variety of functional groups, such as halogen, ester, and cyano, were well tolerated in this transformation. Starting benzylsulfonium salts could be readily prepared from benzyl alcohols by an acid-mediated substitution, increasing the synthetic
