Significance

A one-pot reaction affording chiral chromenes is presented. It proceeds via a domino oxa-Michael-aldol reaction sequence between α,β-unsaturated aldehydes and salicylaldehydes and is promoted by diphenylpyrrolinol triethylsilyl ether. Good to excellent yields and enantioselectivities have been achieved.
