中文摘要: |
本文合成了三种具有多氢键的联萘酚轴手性硫脲催化剂,并将其用于催化合成1,4-二氢吡啶衍生物。结果显示,所合成的新型多氢键硫脲均表现出较好的催化作用,能有效地提高1,4-二氢吡啶衍生物的收率和对映选择性。所有新化合物结构均经过1H NMR、13C NMR、IR、熔点等表征所确认。 |
英文摘要: |
Three kinds of structure-symmetric thiourea catalysts containing multi-hydrogen bond with binol axial chiral were synthesized and successfully applied to the syntheses of 1,4-dihydropyridine derivatives. The results showed that the synthesized polyhydrogen-bonded thioureas have better catalytic activity, which can effectively improve the yield and enantioselectivity of the 1,4-dihydropyridine derivatives. All new compounds were characterized by 1H NMR、13C NMR、IR、melting point and so on. |
