Abstract: The reaction of 1,2‐zwitterionic complexes of 2‐arylcyclopropane‐1,1‐dicarboxylates (ACDC), generated using gallium trichloride, with conjugated substituted diacetylenes was studied. The series of the substituted 1,1′‐binaphthalenes were obtained in yields up to 57%. The reaction occurs via… read more here.

Abstract: The reactions of 1,2-zwitterionic complexes, generated from 2-arylcyclopropane-1,1-dicarboxylates (ACDC) or benzylidenemalonate and gallium trichloride, with benzyl azide proceeds as a formal [3+2] cycloaddition to form dihydro-1,2,3-triazoles. The latter, when the reaction mixture is treated with… read more here.

Abstract: Asymmetric ring-opening reactions of donor–acceptor cyclopropanes with 1,3-cyclodiones have been established for the synthesis of enantioenriched γ-hydroxybutyric acid derivatives in the presence of Cu(ii)/trisoxazoline catalyst. These reactions offered the desired products in 70% to 93%… read more here.
