Host-guest inclusion complexes

Reaction Control of Guest Compounds in Host-Guest Inclusion Complexes... 

When guest molecules are arranged together in the channel of a host-guest inclusion complex, intermolecular reactions of the guest compound may proceed stereoselec-tively and efficiently. An enantioselective reaction is expected when optically active host compounds are used.

Host-Guest Inclusion Complex Formation between Surfactant Stilbenes and Amylose... 

When a mixture of acetophenone 59a (1.0 g, 8.3 mmol), NaBH4 (0.94 g, 24.9 mmol), and water (10 ml) was stirred at room temperature for 2 h, rat-60a was produced. To the water suspension medium of rac-60a was added powdered 8a (3.87 g, 8.3 mmol), and the mixture was stirred for 3 h to give a 2 1 inclusion complex of 8a with (-)-60a.25 Inclusion complex formed was filtered and dried. Heating of the complex in vacuo gave (-)-60a of 95% ee (0.42 g, 85%). From the filtrate left after separation of the inclusion crystals, (+)-60a of 77% ee (0.35 g, 70%) was obtained by extraction with ether. By the same procedure, optically active 60a and 60c-g were prepared (Table 5). Solid state and solvent-free organic reactions have been well established25,263 0. Host-guest inclusion complexation in the solid state has also been reported.260...
