✦ Synopsis

Chiral allyltitaniums having an amino substituent at the C-4 position are prepared from optically active allylic alcohol derivatives I and a Ti(O-i-Pr)4/2i-PrMgCl reagent, which, in turn, react with aldehydes regio-and stereoselectively to afford 3-amino-2-vinylalkanols in excellent yields.
