โฆ Synopsis
Novel 1-(dihydroxypropyl)-5-substituted uracils were synthesized in the reaction of 1-(4-nitrophenyl)-5-substituted uracil derivatives with appropriate aminopropanediols under mild conditions. In the case of 3-amino-1,2-propanediol both racemic and enantiomerically enriched products were obtained. These compounds may be considered as new building blocks for oligonucleotide synthesis.
