Quinine effectively catalyzes an intramolecular Michael-type addition of 7-hy&oxy-8tigloylcoumarin to give a diastereoisomeric mixture of the corresponding cyclized coumarin with a 2,3dimethyl-4-chromanone skeleton. Satisfactory enantioseleetivity was observed in a cis-chromanone construction, but n
