If metalloenzymes could react through abiotic intermediates like these, then the scope of enzyme-catalysed reactions would expand. Here we show that zinc-containing carbonic anhydrase enzymes catalyse hydride transfers from silanes to ketones with high enantioselectivity. We report mechanistic data ...
The effect of temperature on the enantioselectivity of the oxazaborolidine-catalyzed asymmetric borane reduction of ketones has been investigated carefully using alkyl aryl ketones with a variety of functional groups and a B-methoxyoxaza... J Xu,T Wei,Q Zhang - 《Journal of Organic Chemistry》 被...
However, many approaches are precluded from usage by compounds comprising acid-sensitive functional groups due to the severe conditions tangled or the need for significant quantities of Lewis acid. Further Choi et al. developed a unique strategy for deoxygenation of aryl ketones by means of gallium ...
