Summary

On the basis of mass and IR spectra it has been established that the substance with mp 169°C known in the literature as “the acetyl derivative of gossypetin 3,3′,4′,5,8-pentamethyl ether” is in actual fact gossypetin hexamethyl ether.

Thus, yet another case of the migration of a methoxy group from partially etherified compounds in an alkylationprocess has been described.
