Sugars bearing an isothiocyanate moiety at C-1 react with diazadienium iodide to afford glycosyl triazines that represent, through an easy cyclocondensation reaction step, a flexible entry to different nucleoside analogues. We herein demonstrate that this [4+2] cycloaddition reaction occurs with total regiocontrol and good yields. Subsequent transformation of the thiocarbonyl into a carbonyl, and nucleophilic substitution of the methylsulfanyl group by ammonia, yields the 5-azacytidine analogues. All compounds were fully characterised by IR, HRMS, and 13C and 1H NMR (COSY, HMBC and HMQC). Georg Thieme Verlag.

Peracylated glycofuranosyl isothiocyanates are obtained under smooth conditions starting from the corresponding glycosyl chloride by reaction with potassium thiocyanate in anhydrous acetone at room temperature, classical conditions for the synthesis of gl
