Abstract

A simple treatment of fully aroylated purine and pyrimidine ribo-nucleosides with pulverized potassium tert-butoxide in tetrahydrofuran (THF) or dichloromethane under a controlled condition gave a mixture of the corresponding di-O-aroyl derivatives in which 2'-OH derivatives are preponderant over 3'-OH derivatives; 3', 5'-di-O-benzoyluridine, N 4, 3', 5'- tribenzoylcytidine, N 4, 3', 5'-tri-o-toluoylcytidine, N 2, 3', 5'-tribenzoylguanosine, and N 2- ...
