Two novel chiral Bronsted acids 3b and 3c were prepared without involving the complexity of Suzuki coupling. Catalyst 3c bearing two additional hydroxyl groups at 3 and 3′ positions of axially chiral 1,1-binaphthalene-2,2′-diol phosphoric acid was applied

A new series of BINOL-derived multidentate Br?nsted acid catalysts has been developed for the enantioselective addition of the d 1-synthon, methyleneaminopyrrolidine, to N-Boc imines, yielding the versatile, protected α-aminohydrazone intermedi

A series of new 3,3′-disubstituted BINOL derivatives have been synthesised. In a preliminary study, the asymmetric induction of these ligands was investigated in the addition of diethyl zinc to benzaldehyde in the absence of Ti(Oi-Pr)4. This showed different enantioselectivity and activity from those of the unsubstituted BINOL.
