T. Niinomi et M. Sisido, SYNTHESIS OF 2'(3')-O-AMINOACYL-PDCPA CARRYING A PHOTOFUNCTIONAL NONNATURAL AMINO-ACID, Chemistry Letters, (8), 1993, pp. 1305-1308
A mixed dinucleotide pdCpA, was synthesized and characterized by spect
roscopic as well as enzymic analysis. The dinucleotide was acylated wi
th an N-protected nonnatural amino acid (Boc-azoAla). The acylation wa
s found to occur at the 2'(3')-O position exclusively.
