Abstract
Conformationally flexible NUPHOS-type diphosphines have been resolved as their diastereopure platinum BINOLate complexes δ- and λ-[(NUPHOS)Pt{(S)-BINOL}] and the corresponding enantiopure Lewis acids δ- and λ-[(NUPHOS)Pt(OTf)2], being generated by protonation with trifluoromethanesulfonic acid, act as highly efficient catalysts for the hetero-Diels-Alder reaction of nonactivated conjugated dienes with aryl glyoxals and glyoxylate esters, giving ee's as high as 99%.
