✦ Synopsis
The memory effect of the D-threitol-or L-threitol-imprinted 160lfullerene-bisadduct [(fc)-4 or (fA)-4], which was obtained from the double addition reaction between [601fullerene and D-threitol-or L-threitol-boronic acid 1:2 complex (D-1 or L-I), was discussed. In the competitive complexation with D-threitol and L-threitol, (fc)-4 or (fA)-4 diastereoselectively rebound with the original template, Dthreitol or L-threitol, respectively, affording the corresponding 1:1 complex [(fc)-3D or (fA)-3LI. The selectivities increased with lowering the complexation temperature: under the optimum conditions 48% diastereomeric excess was achieved.
