Application of Different Spectral Methods to Examine Structure of the Complexes Found in the Cycloaddition Reactions of 4-Trifluoromethylbenzonitrile Oxide to Olefins

Application of chiral ligands: carbohydrates, nucleoside-lanthanides and other Lewis acid complexes to control regio- and stereoselectivity of the dipolar cycloaddition reactions of nitrile oxides and esters

“…Interactions of the catalytic complex with amide and alcohol type dipolarophiles were described in one of our previous papers. 26 The same steric factors favour also regioselectivity of the process, which is most pronounced for t-butyl (Table 3, reaction no. 14), 2-furanyl (Table 3, reaction no.…”
