title: The base catalysed anomerisation of beta-5-formyluridine; crystal and molecular structure of alpha-5-formyluridine.
abstract: On treatment with strong base beta-5-formyluridine undergoes an anomerisation to give a mixture of the alpha- and beta-anomers. The anomers have been separated by fractional recrystallisation and the absolute configuration of the alpha-anomer has been determined by X-ray analysis.
