## Abstract 2βDeoxyβDβribose (1) was converted into its methyl glycofuranoside 2, which was treated with 4βbiphenylcarbonyl chloride to give a separable mixture of 3 (26%) and 4 (40%). Compounds 3 and 4 were deoxygenated by Barton deoxygenation to give the corresponding 2,3βdideoxyribose derivative
The syntheses of 3-(Z-pyrrolyl)-and 3-(Z-furanylj-indoles are described via the ring-closure of 2-(Z-nitrophenylethenylj-pyrroles or -furans, respectively, with triethylphosphite. The necessary starting compounds are obtained by Lewis acid mediated Michael type addition reactions of either pyrroles
