Chiral spirobinaphtopyrans 1-9 were synthesised using the acid catalyzed aldol condensation of 2-hydroxy-1-naphthaldehyde or 1-hydroxy-2-naphthaldehyde with the appropriate ketone and subsequent reaction of the isolated pyrylium salt with base. Separation or enrichment of enantiomers was accomplishe
