Nitrosylsulfuric acid in the synthesis of 5-chloroisoxazoles from 1,1-dichlorocyclopropanes
摘要:
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.

High-precision experimental kineticisotopeeffects were measured at naturalabundance for the cycloaddition of dichlorocarbene to 1-pentene. These values were compared to isotopeeffects predicted for the addition of dichlorocarbene to propene at the B3LYP/6-31G* and B3LYP/6-311+G* levels. The results provide unambiguous evidence for a nonlinear attack in which bond formation is more advanced at the
