Chiral allyltitaniums prepared from cyclic carbamate of optically active 4-aminoalk-1-en-3-ols and a reagent react with aldehydes with good to excellent regio- and stereoselectivity to afford optically active 1,5-amino alcohols, from which optically active 2,6-cis-disubstituted piperidines are synthesized.
