Furthermore, starting from no-carrier-added [¹⁸F]TBAF, a simple one-pot, two-step cascade method was developed for the generation of ¹⁸F-labeled heterocycles with high radiochem. purity. In the experiment, the researchers used many compounds, for example, tert-Butyl (4-chlorophenyl)carbamate (cas: 18437-66-6Application In Synthesis of tert-Butyl (4-chlorophenyl)carbamate).

Synthesis, biological activity, and docking studies of new acetylcholinesterase inhibitors of the bispyridinium type was written by Kapkova, Petra;Stiefl, Nikolaus;Suerig, Ulf;Engels, Bernd;Baumann, Knut;Holzgrabe, Ulrike. And the article was included in Archiv der Pharmazie (Weinheim, Germany) in 2003.Synthetic Route of C7H5ClF2 This article mentions the following:

A novel series of acetylcholinesterase (AChE) inhibitors of the bispyridinium type was synthesized and the inhibitory activity against AChE and butyrylcholinesterase (BChE) measured. In essence, the substitution pattern influenced the inhibitory potency against AChE, where the most active bispyridiniumoxime (TMB-4) was bisbenzyl substituted followed by monobenzyl substituted, bismethyl substituted, and unsubstituted derivatives of TMB-4. Hence, the bisbenzyl ether of TMB-4 was further investigated. In order to obtain diverse lipophilic and electronic properties for these bisbenzyl bispyridinium derivatives (so-called DUO series), the lateral ring substitution was systematically varied. The lowest IC₅₀ value against AChE found thus far in the DUO series was 0.34 μM. Docking studies were carried out to elucidate the differences in biol. activity. A general binding mode for nearly all compounds could be identified by these investigations. In this binding mode, the docked ligands span the narrow, deeply buried active-site gorge, interacting with Trp84 at the bottom of the gorge, Tyr334 or Phe331 halfway down the gorge, and Trp279 at the peripheral anionic site at the mouth of the gorge. For specific ligands, addnl. interactions were found which helped to explain their deviating activity. Based on the promising characteristics of the novel acetylcholinesterase inhibitors presented, a series of structurally related, optimized candidates will be developed. In the experiment, the researchers used many compounds, for example, 2-(Chloromethyl)-1,3-difluorobenzene (cas: 697-73-4Synthetic Route of C7H5ClF2).
