Abstract

Resolution of gram quantities of a subtly chiral polyoxometalate (POM; the chirality originates from substitution of one metal in the nanosized framework) is possible by reaction with small peptides. Functionalizable acyl polyoxotungstate (TBA)61-P2W17O61{SnCH2CH2C([DOUBLE BOND]O)}] (see picture) can be resolved by kinetic resolution. This approach paves the way for applications of chiral POMs ranging from asymmetric catalysis to their bioactivity.
