Synthesis of 6,8-diarylimino-7H-pyrano[3,2-c:5,6-c'] dicoumarins; chemoselective hydrolysis of the ether-and imino-functions

POCl3-induced dehydration of 3,3′-methylenedi(2-arylamino- 4H-chromen-4-ones) gives 6,8-diarylimino-7H-pyrano[3,2-c:5,6-c']dicoumarins, which undergo chemoselective hydrolysis of the imino function to form 7H-pyrano[3,2-c:5,6-c']dicoumarins by heating with HCl in methanol However, cleavage of the ether function occurs upon heating in acetic acid to give 3,3′-methylenedi(2-arylamino-4H-chromen-4-ones).
