Allyl group as a protecting group for internucleotide phosphate and thiophosphate linkages in oligonucleotide synthesis: facile oxidation and deprotection conditions
Org Lett 2000 Feb 10;2(3):243-6.PMID:10814292DOI:10.1021/ol9910518.
[reaction: see text] The allyl group, which serves as a protecting group for an internucleotide bond for both phosphates and phosphorothioates, can be easily removed by good nucleophiles under weakly basic or neutral conditions. For a practical synthesis on solid support, camphorsulfonyloxaziridine was used as the oxidizing agent for synthesizing DNA, while the Beaucage reagent was used for preparing phosphorothioate oligomers. Both types of oligonucleotides were easily deprotected by concentrated ammonium hydroxide containing 2% mercaptoethanol.
Use of 1,2,4-dithiazolidine-3,5-dione (DtsNH) and 3-ethoxy-1,2,4-dithiazoline-5-one (EDITH) for synthesis of phosphorothioate-containing oligodeoxyribonucleotides
Nucleic Acids Res 1996 May 1;24(9):1602-7.PMID:8649975DOI:10.1093/nar/24.9.1602.
Previous methods for the preparation of phosphorothioate-containing oligodeoxyribonucleotides rely on the reaction of phosphite triesters with sulfurizing reagents such as tetraethylthiuram disulfide (TETD) and 3H-1,2-benzodithiol-3-one 1,1-dioxide (Beaucage reagent). However, these and other sulfurizing reagents suffer from several disadvantages, and there is great impetus for the development of improved methods for sulfur transfer that are fully compatible with standard automated DNA synthesis. The present report describes the use of 1,2,4-dithiazolidine-3,5-dione (DtsNH) and 3-ethoxy-1,2,4-dithiazoline-5-one (EDITH) as effective sulfurizing reagents that meet these needs. Both reagents are easily prepared, and are stable upon prolonged room temperature storage in acetonitrile solution. The reagents are used at low concentrations (0.05 M) and for short reaction times (30 s). The methodology has been proven for the automated synthesis on 0.2-1.0 micromol scales of oligodeoxyribonucleotides, of length 6-20 bases, containing the phosphorothioate substitution at either a single site or at all positions.
