A convenient large-scale synthesis of methyl α-maltoside: a simple model for amylose

Abstract Methyl 4- O -( α - d -glucopyranosyl)- α - d -glucopyranoside (methyl α -maltoside), a model compound for amylose, has been synthesized in four steps and 63% overall yield from relatively inexpensive d -(+)-maltose.

Novel Catalysts for Olefin Cleavage Using Hydrogen Peroxide

Abstract Transition metal oxides are well-known reagents for cleaving olefinic double-bonds. Due to toxicity and expense, catalytic amounts of the metal species, along with a co-oxidant are favoured. Whilst hydrogen peroxide and ruthenium give good results for many olefins, poor results are obtained for, amongst others, terminal double bonds. This paper reports the use of a second metal to extend the range of cleavage reactions using hydrogen peroxide as oxidant, with good efficiency of peroxide usage.
