The invention provides a novel method for producing an oligonucleotide using a nucleoside or oligonucleotide that is easy to isolate and has high storage stability. The oligonucleotide production method includes a step of subjecting a nucleoside or oligonucleotide having a pseudo solid phase-protecting group in at least one location selected from the group consisting of 2'-position, 3'-position, 5'-position and a nucleobase moiety and having a 5'-hydroxyl group or a 3'-hydroxyl group, to H-phosphonation to convert the 5'-hydroxyl group or the 3'-hydroxyl group into an H-phosphonated form.
Ultrasound treatment of dihydropyrrole derivatives with N-sulfenylphthalimides in the presence of base gave the corresponding N-sulfenyldihydropyrrole derivatives.
