Carbohydrate-derived iminium salt organocatalysts for the asymmetric epoxidation of alkenes
A new family of carbohydrate-based dihydroisoquinolinium salts has been prepared and tested for potential as asymmetric catalysts for the epoxidation of unfunctionalized alkene substrates, providing up to 57% ee in the product epoxides.

Acid-catalysed rearrangement of glycosyl trichloroacetimidates: a novel route to glycosylamines
A novel route to glycosylamines has been developed. Treatment of glycosyl trichloroacetimidates with TMSOTf under glycosylation conditions, but in the absence of an acceptor, resulted in complete rearrangement of the trichloroacetimidates into the corresp
