Cyclopentanols were synthesized by a "one-pot" method involving (CpZrCl2)-Zr-2-catalyzed cycloalumination of alpha-olefins with trialkylalanes followed by the in situ reactions of aluminacyclopentanes with esters in the presence of catalytic amounts of Cu, Ni or Pd salts and complexes.

Novel ‘one-pot’ catalytic methods for the synthesis of cyclopentanols, tetrahydrothiophenes, silacyclopentanes and phospholanes are based on successive transformations of olefins and organoaluminium compounds (R2AlR′) in the presence of Cp2ZrCl2 catalyst. In situ generated aluminacyclopentanes serve as common intermediates in these processes.
