The palladium-catalyzed one-pot synthesis of 2,3-deoxy-3-keto aryl C-glycosides is achieved from glycals and anilines in the presence of tert-butyl nitrite and aqueous HBF4 under mild conditions. This one-pot method stereospecifically provides α- and β-aryl glycosides (≥19:1 by NMR) in good yields at room temperature. The configuration at the C-3 position in the glycal determines the anomeric selectivity (i.e., α or β) of the desired products.

The One

A new synthesis of μ-oxo dimeric iron(III) porphyrins from meso-tetraarylporphyrins in one-pot procedure is reported. μ-oxo dimeric iron(III) porphyrin was obtained in high yield (up to 93%) from the reaction of meso-tetraarylporphyrin with ferrous chloride in DMF at pH 8–11. Compared with other synthetic methods of μ-oxo dimeric iron(III) porphyrin from meso-tetraarylporphyrins, the one-pot procedure has higher yields of μ-oxo dimeric iron(III) porphyrins and is a simpler and more convenient procedure. In order to evaluate the range of applicability of this method, μ-oxo dimeric iron(III) porphyrins with different substituents were prepared by the reaction of the corresponding meso-tetraarylporphyrins with ferrous chloride. The results showed that it was possible to apply this one-pot procedure to the synthesis of other μ-oxo dimeric iron porphyrins in excellent yields. A mechanism for the formation of μ-oxo dimeric iron porphyrins was proposed based on the reaction intermediates characterized by HPLC and UV-vis methods.

A high yield of HMF is directly obtained from aquatic microalgae over a commercial acidic zeolite under mild conditions. Experimental results reveal that proteins and lipids in microalgal cells benefit the HMF stability in water.
