the bases in the suitably modified intermediates bearing reactive functions at the base moiety. The diesters were converted to the corresponding monoesters by sodium azide treatment, while the free acids were obtained from the diester by successive treatment with bromotrimethylsilane and hydrolysis. None of the PME derivatives in the pyrimidine series, their 6-aza or 3-deaza analogues, exhibited any

A new hydrogenbondsystem is formed by the transfer of a proton from nitroamino to form nitroimino. The proton and the oxygen in nitroimino form an intramolecular hydrogenbond and two intermolecular hydrogen bonds that shorten the distance between molecules both vertically and horizontally leading to higher density.
