Abstract
(English)
|
Racemic diallyl and di(2-methylallyl) 1,1'-binaphthyl-2,2'-diyl diethers undergo a diastereoselective Wittig rearrangement. After Sharpless-Katsuki epoxydation, one enantiomer can be recovered unchanged and subsequently oxidized to afford chirally pure 1,1'-binaphthyl-2,2'-dicarboxylic acid. Hydrogenation of the intermediate and base-promoted condensation with chlorodiphenylphosphine leads into the little explored, but promising class of atropisomeric phosphinites. Due to the retirement of the subsidy recipient, no research work was carried out in the laboratory during all 2006. On the other hand, the results previously obtained were disseminated by lectures and printed publications.
