Abstract

d-GGAATTCC (XI) was prepared by phosphomonotriazolide method in solution. Synthesis of oligodeoxyribonucleotides by phosphite method in solution using methyl phosphodichloridite was studied. Preparation of P-methyl esters of protected d-CA (XVII), d-CAT (XIX), d-TT (XXI) and d-ATT (XXIII) is described. The removal of methyl group from methyl containing phosphotriester by the action of aqueous pyridine is described.
