titleOfInvention | Method for preparing 3'-azido-3'-deoxythymidine |
abstract | The present invention provides a method for preparing 3'-azido-3'-deoxythymidine of the general formula (I) below, which is useful as an antiviral or AIDS treatment. In the process of the present invention, in preparing a compound of general formula (I) from thymidine, a hydroxyl group in the 5'-position is protected by a trityl group (compound of general formula (III ')) or an unprotected thymidine ( Reacting the compound of formula (III)) with O-acetyl salicyloyl crawlide to obtain a compound of formula (II) or formula (II '); Reacting a compound of formula (II) or formula (II ′) with (PhO) 2 PON 3 or Ph 3 P-NH 3 -diethyl azodicarboxylate; And optionally removing the protecting group of the hydroxyl group at the 5'-position.n n n n n n n n (The compound in which 5′-position is —OR in the formula is (III ′).)n n n n n n n n (The compound whose 5'-position is -OR in the formula is (II ').)n n n n n n n n (Wherein R is a trityl group) |
