Abstract: The memory effect of the D-threitol- or L-threitol-imprinted fullerene-bisadduct [(C-f)-4 or ((f)A)-4], which was obtained from the double addition reaction between 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, (C-f)-4 or ((f)A)-4 diastereoselectively rebound with the original template, D-threitol or L-threitol, respectively, affording the corresponding 1:1 complex [(C-f)-3D or((f)A)-3L]. The selectivities increased with lowering the complexation temperature: under the optimum conditions 48% diastereomeric excess was achieved. (C) 1999 Published by Elsevier Science Ltd.
