Asymmetric addition of chiral triquinphosphoranes on activated carbonyl compounds
Chiral triquinphosphoranes react with trifluoroacetophenone, ketopantolactone and aromatic aldehydes affording pairs of hydroxyphosphoranes diastereomers with a diastereoselectivity up to 90% depending on the nature of the electrophile. In the case of ketopantolactone, hydroxyphosphorane diastereomers are quantitatively converted to alkoxyphosphoranes with a decreasing of diastereomeric excesses. The major alkoxyphosphorane diastereomer exhibits a close SP structure determined by x-ray diffraction analysis.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Electric Literature of 13031-04-4. In my other articles, you can also check out more blogs about 13031-04-4
