This paper deals with the synthesis of a stable biotin-phosmidosine conjugate molecule 3 that is required for isolation of biomolecules that bind to phosmidosine (1). It was found that introduction of a biotin residue into the 6-N position of phosmidosine could be carried out by reaction of an N 7-Boc-7,8-dihydro-8-oxoadenosine derivative 13 with phenyl chloroformate followed by displacement with a diamine derivative 6 along with the simultaneous removal of the Boc group and one of the two phenoxycarbonyl groups and the successive condensation with an N-tritylated biotin derivative 5. The condensation of an N-prolylphosphorodiamidite derivative 4 with an appropriately protected 7,8-dihydro-8-oxoadenosine derivative 17 having the biotin residue gave the coupling product 18, which was deprotected to give the biotin-phosmidosine (O-ethyl ester) conjugate 3.

-
Paragraph 0076-0081, (2019/01/23)
The invention discloses a long-chain biotin marker and a preparation method and application thereof. The long-chain biotin marker comprises a biotin molecule, a spacer arm and a reaction group. The biotin molecule comprises a ring structure and a valeric acid side chain, a structure formula (I) of the spacer arm is as shown in the specification, a structural formula (II) of the reaction group is as shown in the specification, the valeric acid side chain in the biotin molecule is connected with NH at a first tail end of the spacer arm, oxygen at a second tail end of the spacer arm is combined with phosphorus in the reaction group to form an O-P bond, and accordingly connection between the spacer arm and the reaction group is realized. The long-chain biotin marker is used for gene capturingand sequencing.
