synthesized as reversible thiol conjugate addition acceptors. These thia-conjugate additions can rapidly and reversibly achieve equilibrium under aqueous conditions at neutral pH. Kinetic studies show that electron-withdrawing groups at the 4-position of the phenyl ring of the benzalcyanoacetamides promote the conjugate addition at equilibrium. Dynamic thiol exchange of these conjugate acceptors is faster
Benzalcyanoacetamides 被设计和合成为可逆硫醇共轭加成受体。这些硫杂结合物的添加可以在中性 pH 值的水性条件下快速且可逆地达到平衡。动力学研究表明,苯并氰基乙酰胺苯环 4 位的吸电子基团促进了平衡时的共轭加成。这些共轭受体的动态硫醇交换比单独激活的 α,β-不饱和羰基化合物更快。这些硫杂结合物可以组装成动态组合化学中潜在有用的成分。
