Lithio iodomethyl phenyl sulfoxides reacted with alkyl halides and carbonyl compounds to give adducts in good to moderate yields. Solvolysis of the carbonyl adducts led to sulfones or the ring expanded product. 相似文献

NMR isotope shifts at 13C nuclei due to deuteriation in the 2-methyl-2-bicyclo[2.1.1]hexyl cation are reported. Comparisons are made to the 2-methyl-2-bicyclo[2.2.1]heptyl and 2-methyl-2-bicyclo[2.2.2]octyl cations, and also to neutral molecules containing the bicyclo[2.1.1]hexyl framework. The combination of isotope effects with temperature dependence of 13C chemical shifts allows predictions of the shapes of the energy surfaces along the bending coordinate corresponding to bridging in these cations. 相似文献

The reaction of lithio α-chloromethyl phenyl sulfone with imines gave aziridines in good yields. The resulting aziridines were alkylated and underwent the 1,3-dipolar cycloaddition with dimethylacetylene dicarboxylate to give pyrroles in excellent yields. 相似文献
