摘要

1, 3-Dioxan-5-yl diazoacetates are valuable substrates for highly diastereoselective and enantioselective carbon-hydrogen insertion reactions. trans-2-(tert-Butyl)-1, 3-dioxan-5-yl diazoacetate is a direct precursor to 2-deoxyribono-1, 4-lactone in up to 81% ee, whereas cis-2-(tert-butyl)-1, 3-dioxan-5-yl diazoacetate yields only the protected 2-deoxyxylono-1, 4- lactone in up to 96% ee. However, trans-2-aryl-1, 3-dioxan-5-yl diazoacetate (aryl= phenyl ...
