  Enantioselective Metallophosphite-Catalyzed C-Acylation of Nitrones

  摘要：

  Metallophosphites derived from tartaric acid catalyze the enantioselective addition of acyl silanes to nitrones. The product alpha N-silyloxyamino ketones are obtained in moderate to good yields (36-94%) with excellent enantioselectivity (er >= 95:5). The nitrone oxygen is essential in facilitating the silyl transfer that is required for catalyst turnover. This represents, to the best of our knowledge, the first example of C-acylation of nitrones and the most highly enantioselective catalytic addition of an acyl anion equivalent to an azomethine electrophile. The N-O bond of the product may be reductively cleaved under mild conditions to provide N- aryl alpha-amino ketones with negligible loss of enantiopurity.
