An unusually facile [3,3]-sigmatropic rearrangement in a stereospecific synthesis of novel 2′,3′-dideoxynucleoside precursors

Article abstract of DOI:10.1016/0040-4039(95)00747-Z

The glycal 5 is converted to intermediates which undergo, under mild conditions, thermal aza-Claisen rearrangements, leading to the amides 7 and 8 and the 2-pyrimidone 9, all potential precursors to 2′,3′-dideoxynucleosides.
