A new method for the synthesis of primary amides from alkenyl iodides in one carbonylation step using ammonium carbamate as ammonia synthon is reported. The products were obtained in good yields under mild reaction conditions using CO (1-6 bar). Steroidal substrates with various moieties (e.g., 6-OH group, lactams, or aromatic A-ring) could be converted selectively into the products.
报道了一种使用氨基甲酸铵作为氨合成子在羰基化步骤中由链烯基碘合成伯酰胺的新方法。使用 CO (1-6 bar) 在温和的反应条件下以良好的收率获得产物。具有各种部分(例如,6-OH 基团、内酰胺或芳族 A 环)的甾体底物可以选择性地转化为产物。
