    摘要:
    报道了几种环状二烷氧基原酸酯的合成。这些原酸酯在动力学控制条件下的酸水解仅产生相应的羟基酯。构象刚性环状混合原酸酯通过仅失去轴向烷氧基而得到羟基酯。环状原酸酯可以有九种不同的gauche构象。结果表明,它们仅通过一种 gauche 构象异构体水解。这些结果带来了进一步的实验证据,表明酯类水解中四面体中间体的裂解存在立体电子控制。

  • Method of inhibiting nonspecific interaction between molecules on solid phase support
    申请人:Tanaka Akito
    公开号:US20060177943A1
    公开(公告)日:2006-08-10
    The present invention provides a method of suppressing the nonspecific interaction between molecules, characterized in that in a process to immobilize a molecule onto a solid phase carrier and analyze the specific interaction between the molecule and a molecule that specifically interacts with the molecule on the solid phase, the hydrophobic property of the solid phase surface in the solid phase carrier is regulated, particularly a hydrophilic spacer is interlaid at the time of immobilization of the molecule onto the solid phase carrier, which method makes it possible to suppress the nonspecific interaction between the molecules, and to reduce nonspecific adsorption to the solid phase.
    本发明提供了一种抑制分子之间非特异性相互作用的方法,其特征在于在将分子固定到固相载体并分析与固相上特异性相互作用的分子之间的过程中,调节固相载体中固相表面的疏水性质,特别是在将分子固定到固相载体时,交错放置了亲水性间隔物,该方法使得能够抑制分子之间的非特异性相互作用,并减少对固相的非特异性吸附。
