摘要:The combined Lewis acid catalytic system, generated from (R)-1,1'-bi-2-naphthol [(R)-BINOL], Ti(O-i-Pr)(4), H2O, and lithium chloride, effectively catalyzed the enantioselective vinylogous aldol reaction of Brassard's diene with aromatic aldehydes affording the (Z)-delta-hydroxyl-alpha,beta-unsaturated esters exclusively in good yields with excellent enantioselectivities (90-99% ee) under mild conditions. A Lewis acid Lewis acid bifunctional working model was proposed for the catalytic process based on some control experiments.
