TADDOL derivatives and the Ca²⁺-salts of tartaric acid derivatives were found to be versatile and generally applicable resolving agents for the preparation of the enantiomers of P-stereogenic heterocyclic phosphine oxides and phosphinates.

The first crystal structure to be determined for an inclusion complex in which a chemically modified cyclodextrin serves as the host reveals a host molecular parent molecule but provides an extended toroidal region in which larger hydrophobic substrate molecules can be accommodated.
