Synthesis of 4-Substituted 3-Hydroxycoumarins

3-Hydroxycoumarin on fusion (10 hr; 130-150 deg C) with aromatic aldehydes yields substituted 4,4'-benzal-bis-(3-hydroxycoumarin) (Ia-c).Ic on heating with acetic anhydride gives 4,4'-p-bromobenzal-bis-(3-acetoxycoumarin) (II).On the other hand, 3-hydroxycoumarin on fusion (20 hr; 130-150 deg C) with aromatic aldehydes affords the substituted 6H,8H,14H-bisbenzopyranopyran-6,8-diones (IIIa-c).
