摘要

A new method for the synthesis of fluorescent nucleosides has been developed. It has been shown that a reaction of benzoquinone with aminopropenyl group at C-5-position of 2'-deoxyuridine or 2'-deoxycytidine and aminopropynyl group at the C-7-position of 8-aza-7-deazaadenosine under extremely mild conditions affords conjugated benzoxazole derivatives of nucleosides, which possess strong fluorescent properties. In a similar reaction 5'-amino-5'-deoxy-nucleosides form double-headed nucleoside derivatives with benzoxazole attached at C-4'-position.
