Recoverable fluorous CBS methodology for asymmetric reduction of ketones.

[reaction: see text]. An operationally simple and recoverable fluorous CBS methodology was developed. The in situ-generated fluorous oxazaborolidine efficiently catalyzed the reduction of ketones with high enantioselectivity and reactivity.

Fluorous click chemistry as a practical tagging method.

Highly efficient fluorous tagging methodology was developed based on catalytic 1,3-dipolar cycloaddition as the key step.
