ABSTRACT Nitration of 9-substituted [ethyl, (Ac)2-2′-deoxyribosyl, (Ac)3-ribosyl] N 6-acetyladenine derivatives with Cu(NO3)2·3H2O/Ac2O was examined. Nitration proceeded at the 2-position, although the yield was low. Removal of the acetyl groups gave 2′-deoxy-2-nitroadenosine derivatives.

paper describes a new class of molecular receptors 2 that bind adenine derivatives 3 in aqueoussolution by means of hydrogen bonding (base-pairing). The receptors are supramolecular assemblies of thymine groups embedin micelles, which self-assemble when (thyminylalkyl)ammonium salts 1 [Thy-(CH 2 ) n -N + Me 3 ] are mixed with aqueous sodium dodecyl sulfate (SDS) solutions.
