Catalytic asymmetric prins cyclizations: cation generation and trapping with (BINAP)Pt dications.
[reaction: see text] (R)-[(tolBINAP)Pt(NC(6)F(5))(2)][SbF(6)](2) (5) catalyzes the highly enantioselective Prins reaction between 2-allylphenols and glyoxylate esters. Other Lewis acid catalysts favor glyoxylate-ene products.
