Herein we report the identification of a novel series of 5-piperazinyl-3-sulfonylindazoles as potent and selective 5-HT6 antagonists. The synthesis, SAR, and pharmacokinetic and pharmacological activities of some of the compounds including 3-(naphthalen-1-ylsulfonyl)-5-(piperazin-1-yl)-1H-indazole (WAY-255315 or SAM-315) will be described.

Cascade reactions of ortho-carbonyl-substituted benzonitriles with ((chloromethyl)sulfonyl)benzenes as pronucleophiles led to new isoindolin-1-ones with a tetrasubstituted C-3 position or to (Z)-3-(sulfonyl-methylene)isoindolin-1-ones. The reactions start from readily available materials, are carried out under mild conditions, and do not require metal catalysis. Promoted only by the cheap and environmentally
邻-羰基取代的苄腈与 ((氯甲基)磺酰基) 苯作为亲核试剂的级联反应产生具有四取代 C-3 位的新异吲哚啉-1-或 ( Z )-3-(磺酰基-亚甲基)异吲哚啉-1 -那些。反应从容易获得的材料开始,在温和的条件下进行,不需要金属催化。仅以廉价且环保的 K 2 CO 3为基础,最多可以在一个锅中组合六个元素步骤。因此,连续的一锅级联/β-消除/烷基化为马兜铃内酰胺天然产物的合成提供了有用的中间体。通过 DFT 研究研究了观察到的选择性和机制。

β-Aryl-substituted α,β-epoxysulfones undergo House-Meinwald rearrangement to form α-aryl, α-sulfonyl aldehydes in high yields upon dissolution in hexafluoroisopropanol (HFIP), and in some cases, heating. These compounds are typically isolated as the corresponding alcohols following reduction with NaBH4. The β-aryl group is generally required for rearrangement and a variety of substitution patterns
