Abstract
Isomerization of enantiopure C-2-symmetric 3,5-dihydroxyazepane deriva tives has been studied. The neighboring nitrogen participation occurs during mesylation to give a chloromethylpiperidine, whereas from the L -ido-azepane a chiral bridged morpholine structure (1R-(6endo, 7exo)-8 -oxa-3-azabicyclo[3.2.1] octane-6,7-diol) is obtained under Mitsunobu conditions.
