  Regioselective epoxide opening of epoxyamides derived from d-glucose. Cyclization approaches to azepanes

  摘要：

  Epoxyamides obtained from n-glucose have been evaluated as tools to obtain polyhydroxyazepanes. The stereoselectivity in formation of the epoxyamides was proven to be dependent of the protecting group. The conversion of epoxyamides into epoxyalcohols was necessary to obtain polyhydroxyazepanes, because the direct cyclization of 2-N-amides to azepanecarboxamides was unsuccessful from derivatives obtained from n-glucose. Epoxyamides and epoxyalcohols were regioselectively (alpha) opened by nitrogen nucleophiles. Reduction of diethyl epoxyamide by catalytic transfer hydrogenation gave the alpha deoxy product.
