REGIOSELECTIVE PROTECTION OF CARBOHYDRATE DERIVATIVES. PART. 20. SIMPLE, EFFICIENT 2'-O-DEACYLATION OF FULLY ACYLATED PURINE AND PYRIMIDINE RIBONUCLEOSIDES THROUGH tert-BUTOXIDE

Nishino, Shigeyoshi,Takamura, Hatsuko,Ishido, Yoshiharu

, p. 1995 - 2004 (2007/10/02)

A simple treatment of fully aroylated purine and pyrimidine ribonucleosides 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, N4,3',5'-tribenzoylcytidine, N4,3',5'-tri-O-toluoylcytidine, N2,3',5'-tribenzoylguanosine, and N2,isobutyryl-3',5'-di-O-benzoylguanosine were obtained crystalline in 80 percent, 78 percent, 72 percent, 67 percent, and 65 percent yields, respectively.
