Transformations of gem-dichloroarylcyclopropanes in the reaction with NOCl·2SO3. Synthesis of 3-aryl-5-chloroisoxazoles
摘要:
Nitrosation with complex NOCl center dot 2SO(3) of gem-dichloroarylcyclopropanes containing acceptor substituents in the aromatic ring proceeded chemo- and regioselectively affording 3-aryl-5-chloroisoxazoles in high yields. The presence of donor substituents complicated the reaction by the occurrence of competing processes.

Nitrosylsulfuric acid is shown to be a usable reagent for the synthesis of 5-chioroisoxazoles from readily available 1,1-dichlorocyclopropanes via nitrosation-heterocyclization reaction. A cytotoxicity of some of the prepared 5-chloroisoxazoles towards MCF7, A549, HEK293T and VA13 cell lines was evaluated.
