Asymmetric 2-aluminoethylalumination of mono-substituted alkenes and 2,5-dihydrofurans catalysed by (R,R)-ethylene-1,2-bis(eta(5)-4,5,6,7-tetrahydro-1-indenyl)zirconium (R)-1,1'-binaphth-2,2'-diolate 4 and eta(5)-cyclopentadienyl-eta(5)-(1-neomenthyl-4,5,6,7-tetrahydroindenyl)zirconium dichloride 5. gave 30 - 99% enantiomeric excesses. The so formed organoaluminium has potential for further elaboration leading to enantiomerically enriched products. (C) 1997 Elsevier Science Ltd.
