Photoprotective compositions well suited for the photoprotection of the skin, lips and/or hair against the damaging effect of UV-radiation comprise at least one aqueous phase and at least one system for screening out UV-radiation, and which also contain:
(a) at least one partially or totally neutralized, crosslinked or non-crosslinked amphiphilic polymer of 2-acrylamidomethylpropanesulfonic acid (AMPS), and
(b) at least one water-soluble silicone comprising at least one terminal or pendent monovalent polyoxyalkylene group.

[formula: see text] The kineticresolution of racemic epoxides via catalytic enantioselective rearrangement to allylicalcohols was investigated. Using the Li-salt of (1S,3R,4R)-3-(pyrrolidinyl)methyl-2-azabicyclo [2.2.1] heptane 1 as catalyst allowed both epoxides and allylicalcohols to be obtained in an enantioenriched form.
