Abstract
The memory effect of the d-threitol- or l-threitol-imprinted [60]fullerene-bisadduct [ ( f C)- 4 or ( f A)- 4 ], which was obtained from the double addition reaction between [60]fullerene and d-threitol- or l-threitol-boronic acid 1:2 complex ( d- 1 or l- 1), was discussed. In the competitive complexation with d-threitol and l-threitol, ( f C)- 4 or ( f A)- 4 diastereoselectively rebound with the original template, d-threitol or l-threitol, respectively, affording the corresponding 1:1 complex [ ( f C)- 3D or ( f A)- 3L ]. The selectivities increased with lowering the complexation temperature: under the optimum conditions 48% diastereomeric excess was achieved.
