The object of the present invention is to provide an active oxygen eliminator having high active oxygen elimination effect and can be widely used in foods, drinks, and cosmetics as well as to provide the method for producing the active oxygen eliminator. To this end, the present invention provides an active oxygen eliminator which includes composite particles produced by bonding a platinum group element to dendritic molecules or having the platinum group element included in the dendritic molecules and also provides a method for producing the active oxygen eliminator which includes forming the composite particles by bonding the platinum group element to the dendritic molecules or having the platinum group element included in the dendritic molecules.

The catalytic enantio selective addition of different organozinc reagents, such as alkyl or in situ generated phenylzinc derivatives to simple aryl ketones, was accomplished using titanium tetraisopropoxide and chiral ligands derived from trans-1-arenesulfonylamino-2-isoborneolsulfonylamidocyclohexane and Frechet-type dendrons with up to 2.5 nin of diameter, giving the corresponding tertiary alcohols with enantioselectivities up to >99%. A simple and efficient procedure for the synthesis of the ligands used is also described, involving the radical addition of the corresponding thiol dendron to the chiral styryl-isoborneol derivative.
