RhI-catalyzed [6+2] cycloaddition of alkyne-allenylcyclobutanes: A new entry for the synthesis of bicyclo[6.m.0] skeletons

Bicyclo under construction! The [RhCl(dppp)2]-catalyzed intramolecular [6+2] cycloisomerization of alkyne-allenylcyclobutanes efficiently produced bicyclo[6.4.0]dodecatriene and bicyclo[6.3.0]undecatriene skeletons (see scheme). Straightforward cleavage of the unfunctionalized simple cyclobutane and construction of the bicyclo[6.m.0] frameworks could be achieved under mild conditions.
