    摘要: A method for preparing an oligonucleotide comprising the steps ofa) providing a hydroxyl containing compound having the formula (A), b) reacting said compound with a phosphitylating agent in the presence of an activator (activator I) having the formula (I) to prepare a phosphitylated compound; and c) reacting said phosphitylated compound without isolation with a second compound having the formula (A) wherein R5, R3, R2, B are independently selected, but have the same definition as above in the presence of an activator II different from activator I.
