TPAP-catalyzed direct oxidation of primary alcohols to carboxylic acids through stabilized aldehyde hydrates

We present a simple, mild, and highly effective method for the direct conversion of primary alcohols to carboxylic acids. TPAP serves as the catalyst, and NMO?H2O plays a dual role, acting as the co-oxidant and as a reagent for aldehyde hydrate stabilization. This previously unknown stabilizing effect of geminal diols by N-oxides is the key for the efficiency of the overall transformation.

Application of stabilized sugar-derived phosphoranes in the synthesis of higher carbon monosaccharides. First synthesis of a C21-dialdose

C21 Monosaccharide precursors 11 and 12 were synthesized by a coupling of a C12 aldehyde 1 with C9 stabilized phosphoranes 2 and 3 respectively. The 'smaller' C19 sugar 13 was prepared from a C12 alde
