Abstract
It was shown that under alkaline conditions the cyclonucleoside 1 was converted to an imidazole cyclonucleoside 2, and under milder conditions it was converted to an amidine 3, which reacted with N,N′-thiocarbonyldiimidazole and cyanogen bromide as well as phosgene affording the corresponding ring closure products 8, 9 and 10.
