Three-component and one-pot, reaction between β-naphthol, Meldrum's acid and aryl aldehydes in the presence of piperidine affords 1-aryl-1,2-dihydro-3H-naphtho[2,1-b]pyran-3-ones in excellent yields.

By employing a chiral bifunctional thiourea-tertiary amine as catalyst, domino Michael-type Friedel-Crafts alkylation/cyclization of -naphthols with akylidene Meldrum's acids was realized. The reactions afforded various enantioenriched -arylsplitomicins with good yields (up to 99%) in moderate enantioselectivities (up to 79%). Georg Thieme Verlag Stuttgart · New York.
