Abstract

L ation of their antitumor activity. l Our efforts in this research have uncovered some interesting heterocylic chemistry which we report. It had previously been reported by Cheng and coworkers1 that treatment of 1-chloroanthraquinone (lc) with the potassium salt of 2- (dimethy1amino) ethanol yielded Id (60%, isolated as the hydrochloride salt). Our initial attempt to prepare la was to react IC with 1 equiv of the sodium salt of 2-aminoethanol in ...
