O-silylated α-aminoesters, resulting from the regioselective reaction between organozinc derivatives and α-iminoesters bearing an alcohol group, are transformed into 3-amino-1,5 (or 1,6)-diols; then 2-allylic-3-amino-1,5-diols are converted into 3-prop-1-enylmorpholines or into 5-s-butyl-2,3-dihydro-6H-1,4-oxazines.
