title: NMR analysis of a series of substituted pyrazolo[3,4-d] pyrimidines-4-amines.
abstract: A series of 21 substituted pyrazolo[3,4-d]pyrimidines-4-amines were studied by (1)H and (13)C NMR. The application of two-dimensional techniques, HMQC and HMBC, allowed the complete assignment of the spectra for all the compounds.
