3′‐(1,2,3‐Triazol‐1‐yl)‐2′,3′‐dideoxythymidine and 3′‐(1,2,3‐triazol‐1‐yl)‐2′,3′‐dideoxyuridine

Abstract Cycloaddition of different acetylenic compounds on the azido function of 3′‐azido‐2′,3′‐dideoxythymidine and 3′‐azido‐2′,3′‐dideoxyuridine afforded products with a 1,2,3‐triazol‐1‐yl substituent in the 3′‐position. In contrast with the parent compounds, these triazolyl derivatives had no appreciable activity against human immunodeficiency virus (HIV‐1).
