What is A Novel Salicylaldehyde Based Mineral Supported Expedient Synthesis of Benzoxazinone Nucleosides about?

An expedient mineral (montmorillonite K-10 clay) catalysed cycloisomerisation of salicylaldehyde 4-(b-D D -ribo-or b-D D -2 0deoxyribofuranosyl)semicarbazones yields benzoxazinone nucleosides, 4-hydrazino-3,4-dihydro-3-(b-D D -ribo-or b-D D -2 0 -deoxyribofuranosyl)-2H-benz[e]-1,3-oxazin-2-ones, which readily undergo reductive dehydrazination on alumina-supported copper(II) sulfate to furnish 3,4-dihydro-3-(b-D D -ribo-or b-D D -2 0 -deoxyribofuranosyl)-2H-benz[e]-1,3-oxazin-2-ones under solvent-free microwave irradiation.
