The comparative reactivity of 2,3-dimethyl-and 1,2,3-trimethyl-6-aminoindoles in the reaction with ethyl trifluoroacetoacetate has been studied with the aim of developing the synthesis of corresponding trifluoromethylpyrroloquinolines. Depending on the amine used, the reaction proceeds differently both at the initial stage of the formation of amides and during their transformation into trifluoropyrroloquinolines. 相似文献

The finite nuclear size corrections to the Dirac binding energy of an electron and to the vacuum polarization in hydrogen-like
ions are considered. These corrections were calculated for the 1s
1/2, 2s
1/2, 2p
1/2, and 2p
3/2 states in a wide range of the nuclear charge Z = 1–100. The results obtained are compared with the available analytical data. 相似文献
