Solid-state asymmetric photochemical studies using the ionic chiral auxiliary approach.
The ionic chiral auxiliary approach to asymmetric photochemical synthesis discovered by the Scheffer group has been successfully applied to many reactions in the solid state. Enantiomeric excesses of up to 99% were obtained using this method. After a brief introduction of absolute asymmetric synthesis, chirally modified zeolites and host-guest assemblies in asymmetric photochemistry, the bulk of this review will summarize and discuss the application of the solid state ionic chiral auxiliary technique to the Norrish type II reaction, the di-pi-methane photorearrangement, and to a novel retro-Claisen photorearrangement.
