✦ Synopsis
Alkoxy allylic zirconium reagents, prepared from acet& of a,tWttsaturated a&i&y&s and "Cp$Y, react with carbonyl compounds to give 1 &diols or rhydroxy aldehyde derivatives.
Diastereoselective addition reactions of ralkoxy allylic organometallics to carbonyl compounds are an ideal means for the construction of allylic 1,2-dials, important building blocks for natural products synthesis. metals.1
