PROTECTION OF IMIDE GROUP OF URACIL MOIETY BY MEANS OF 2,2,2-TRICHLORO-TERT-BUTYLOXYCARBONYL CHLORIDE: A SELECTIVE SYNTHESIS OF 2′-O-METHYLURIDINE

Abstract
2,2,2-Trichloro-tert-butyloxycarbonyl group (TCBOC) was useful protecting group for the protection of imide function of uracil moiety. Starting from N3-TCBOC uridine derivative, 2′-O-methyluridine was selectively synthesized without formation of N3-methyluridine derivatives.
