Apart from the mechanistic interest of the present work, the experiments reported above represent a simple, ste- reoselective route to the important amino deoxysugar derivatives 7 and 8 and a general entry to chiral secondary amines. Further synthetic applications of the stereo- chemically rich, highly functionalized chiral synthons 5 and 6 are in progress. ... Acknowledgment.
