The synthesis of the hexanucleotide d)A-C-C-A-G-C), complementary to the 2 major triplets of fibroin mRNA, using the phosphotriester methodology is described. The protected dinucleotides ((MeO)2Tr)dbzA.anC, ((MeO)2Tr)danC.bzA and ((meO)2Tr)dacG.anC were synthesized; the latter two were detritylated and joined in stepwize fashion to the 1st to form the protected hexanucleotide ((MeO)2Tr)dbzA.anC.anC.bzA.acG.anC. The latter was deblocked with NH3 and acid to form the hexanucleotide d(A-C-C-A-G-C). In view of the ability of a prototype affinity column, oligo dC-cellulose, to isolate fibroin mRNA, prospects appear excellent for the d(A-C-C-A-G-C)-cellulose affinity column isolation of fibroin mRNA.
