  First Reported Nonpeptide AT₁ Receptor Agonist (L-162,313) Acts as an AT₂ Receptor Agonist in Vivo

  摘要：

  In this investigation, it is demonstrated that the first nonpeptide AT, receptor agonist L-162,313 (1), disclosed in 1994, also acts as an agonist at the AT(2) receptor. In anesthetized rats, administration of compound 1 intravenously or locally in the duodenum increased duodenal mucosal alkaline secretion, effects that were sensitive to the selective AT2 receptor antagonist PD-123,319. The data strongly suggest that 1 is an AT2 receptor agonist in vivo. To the best of our knowledge, this substance is the first nonpeptidic low-molecular weight compound with an agonistic effect mediated through the AT2 receptor.

• Boron trichloride as an efficient and selective agent for deprotection of tert-butyl aryl sulfonamides
  作者：Yiqian Wan、Xiongyu Wu、Mahalingam A. Kannan、Mathias Alterman

  DOI：10.1016/s0040-4039(03)01020-7

  日期：2003.6

  A fast, mild and selective method for deprotection of tert-butyl aryl sulfonamides utilizing BCl3 as deprotection reagent has been developed. A variety of tert-butyl aryl sulfonamides used under these conditions gave the corresponding primary sulfonamides in high yields. The method does not cleave methoxy groups and prevents incorporation of tert-butyl groups onto electron-rich aromatic rings.

  已经开发了一种快速，温和且选择性的方法，该方法利用BCl 3作为脱保护剂对叔丁基芳基磺酰胺进行脱保护。在这些条件下使用的各种叔丁基芳基磺酰胺以高收率得到相应的伯磺酰胺。该方法不裂解甲氧基，并防止叔丁基结合到富电子芳环上。

  DOI：10.1081/scc-200048949

  日期：2005.1.1

  A mild and efficient method for deprotection of tert-butyl sulfonamide groups utilizing Sc(OTf)(3) as deprotecting reagent has been developed. A variety of tert-butyl aryl sulfonamides used under these conditions gave the corresponding primary sulfonamides in high yields. The Lewis acid catalyst could be fully recovered and reused with maintained activity after the reactions.
