摘要：
One-pot montmorillonite K-10 clay-supported three-component reactions Of Substituted salicylaldehydes, ribosyl/deoxyribosylureas and ammonium acetate expeditiously yield the novel N-nucleosides, 4-amino-3,4-dihydro-3-(beta-D-ribo- or beta-D-2'-deoxyribofuranosyl)-2H-benz[e]-1,3-oxazin-2-ones, via cycloisomerisation of an aldimine intermediate under solvent-free microwave irradiation conditions.
