Abstract
[GRAPHICS] A new concept for the discrete preparation of optical antipodes is reported . The approach makes use of a cyclization/cleavage procedure that has been applied to polymer-supported quasi-meso compound 1, containing a polymeric leaving group and a regular leaving group. Two-directional cyclization lead s to the formation and separation of quasi-enantiomers 2 and 3 simultaneous ly, with one being immobilized and one free in solution. Treatment of 2 and 3 with appropriate nucleophiles gives discrete enantiomers 4 and 5.
