應用

苯肼可用作反应物，进行以下合成反应：
  • 以N-溴磺酰胺作为催化剂，与芳基醛和乙酰乙酸酯反应，通过一锅假五组分合成4, 4′-（芳基亚甲基）-双（3-甲基-1-苯基-1H-吡唑-5-醇）。
  • 通过巯基乙酸和醛或酮处理合成噻唑烷酮。
  • 与6-（三氟甲基）靠曼酸反应合成5-[3,3,3-三氟-2-（苯基肼基）丙基]-1-苯基-1H-吡唑-3-羧酸。

也可作为前体，在Bronsted碱和金属盐为催化剂的条件下，过与碳酸二甲酯（DMC）反应，制备N-1和N-2选择性羧甲基化产物。

Glycan Labeling

Structural modifications of proteins are essential to living cells. When aberrantly regulated they are often the basis of disease. Glycans are responsible for much of the structural variation in biologic systems, and their representation on cell surfaces is commonly called the “glycome.”
