Organocatalytic domino Michael-hemiacetalization of β-tetralones with α,β-unsaturated aldehydes is presented. Treatment of β-tetralones with α,β-unsaturated aldehydes in the presence of diphenylprolinol silyl ether gave 2,3,5,6-tetrahydro-1-alkyl/aryl-1H-benzo[f] chromen-3-ol derivatives with high to excellent chemical yields (50-99%) and high levels of enantioselectivities (up to 96% ee).
