Abstract

Stereospecific and Stereoselective Rhodium(I)-Catalyzed Intramolecular [2 + 2 + 2] Cycloaddition of Allene-Ene-Ynes: Construction of Bicyclo[4.1.0]heptenes. -A novel Rh(I)-catalyzed intramolecular [2 + 2 +2] cycloaddition of allene-ene-ynes yields cyclopropane-fused polycyclic products. -(OHTA, Y.; YASUDA, S.; YOKOGAWA, Y.; KUROKAWA, K.; MUKAI*, C.; Angew.
