Competitive reactions of diisopropyloxy(η²-alkene)titanium on N-allyl diesters derived from natural amino acids and performed under varying conditions (temperature, nature, and concentration of Grignard reagents) show different regio- and chemoselectivities. In light of the isolated reaction products, a possible mechanism of the formation of original products is discussed.
