Amidinium salts Diels-Alder reactions

A novel C2-chiral bis(amidinium) salt can be synthesized from 5-(tert-butyl)isophthalic acid. The salt [tetrakis(3,5-bistrifluoromethylphenyl)borate (TFPB)] contributes to not only rate acceleration but also asymmetric induction in the Diels-Alder reaction of 1 -vinyl-3,4-dihydronaphthalene and cylopentendione, owing to hydrogen bond mediated association of chiral auxihary with dienophile [91] (Scheme 3.NaN). [Pg.82]
