Chiral 2-substituted-2-cyclohexen-1-one 2a is prepared. Conjugate additions of organometallic reagents to 2a occur with good to excellent diastereoselectivities. Enone 2b, which contains an additional potentially coordinating oxygen atom on the side chain of the chiral auxiliary, gave about the same stereoselectivity as 2a. The chiral auxiliary (S)-(+)-2-(methoxymethyl)pyrrolidine can be removed from
