Enantiodivergent Formation of Chiral Product

Their preliminary studies discovered that the two phosphines of (i )-131 operate independently. When the intermediate (i )-133 was isolated and reused in the resolution of racemic 134, the corresponding starting hydroperoxide was obtained in 84% ee with good selectivity. These results suggest that the chiral monophosphines may also be useful for such type of KRs. 

The aryl seleno and methoxy groups could be eliminated from the adduct (137) by using catalytic amount of CF3SO3H in the presence of 2equiv of styrene in order to obtain the other enantiomer of the allylic alcohol.
