Acid-catalysed Condensation of Isoprene with β-Orcinaldehyde: Synthesis of 2,2-Dimethylformylchromans and Synthesis of 5-Methylxanthyletin and Seselin Derivatives

Condensation of β-orcinaldehyde with isoprene in the presence of orthophosphoric acid gives 6-formyl-5-hydroxy-2,2,7-trimethyl-3,4-dihydro-2H-1-benzopyran (3), 6-formyl-7-hydroxy-2,2,5-trimethyl-3,4-dihydro-2H-1-benzopyran (4) and 6-formyl-2,2,5,8,8-penta
