ABSTRACT:
Novel 2-oxy-5-isopropylidene-7-hydroxy-9-substituted-2,6-methano-3,4,5,6-tetrahy dro-2H-1-benzoxocins are prepared by condensing a 5-(substituted)resorcinol with a 1-alkoxy-4-(1-hydroxy-1-methylethyl)-1,4-cyclohexadiene in the presence of a suitable catalyst. The new benzoxocin derivatives are useful in the synthesis of certain dibenzo[b,d]pyran-9-ones, valuable as anti-anxiety, analgesic, and anti-depressant drugs.
