Electrophilic functionalization of N-substituted vicinal alkynyl(amino)cyclopropanes via selective lithiation

N -Alkyl- N -Boc-substituted 1-amino-2-alkynylcyclopropanes undergo selective lithiation at the carbon atom in α-position relative to the triple bond under the action of Bu n Li in THF at −65 °C. Lithiation of the starting compounds representing mixtures of cis - and trans -isomers affords the trans...
