Asymmetric biomimetic transamination is a highly attractive method for synthesis of chemically and biologically important chiral amino acids and chiral amines. Development of chiral pyridoxamines/pyridoxals is the key for the reaction. New axially chiral biaryl pyridoxamines based on H4-naphathene skeleton have been developed. The pyridoxamines display good enantioselectivity and high catalytic activity
不对称仿生转氨反应是合成化学和生物学上重要的手性氨基酸和手性胺的极具吸引力的方法。手性吡ido胺/吡rid醛的开发是反应的关键。已经开发了基于H 4-萘基骨架的新的轴向手性联芳基吡ido胺。吡ido胺在α-酮酸的不对称仿生转氨反应中表现出良好的对映选择性和高催化活性,可提供多种旋光性非天然氨基酸,产率为61-98%,ee可达91%。
