Highly stereoselective alkylative and arylative cyclization reactions of allenyl-aldehydes and -ketones with organozincreagents occur efficiently in the presence of catalytic Ni(COD)2 to afford cis-fused homoallylic cyclopentanols.

Cyclizations of allenyl aldehydes and intermolecular couplings of allenes and aldehydes provide a direct procedure for the preparation of homoallylic alcohols. The couplings and cyclizations involve the use of diorganozine reagents as reducing agents and Ni(COD)(2) as the catalyst. (c) 2005 Elsevier Ltd. All rights reserved.
