The construction of a novel series of enantiopure tetrahydrofuranyl 1,2,3-triazolyl C-nucleoside analogues utilizing click reaction of sugar derived tetrahydrofuranyl alkynes with various ‘in house’ synthesized sugar derived tetrahydrofuranyl azides and an adamantyl azide is described. The biological significance of the synthesized C-nucleosides was highlighted by evaluating them in vitro for anti-bacterial

applied to the synthesis of symmetrical butadiynyl (32―37), octatetraynyl (47) and do-decahexaynyl (49) polyynes. The unsymmetrically substituted diynes 39, 40 and 41 and triynes 43 and 44 were synthesized by coupling reaction between the newly synthesized bromoalkyne/diynes 38/42 and commercially available (trialkylsilyl)acetylenes. Syntheses of the 1,2,3-triazolyl-C-nucleoside analogue 51 and of the
