标 题 :Process for the synthesis of modified P-chiral nucleotide analogues
发明人：STEC WOJCIECH J; WOZNIAK LUCYNA A; CHWOROS ARKADIUSZ; PYZOWSKI JAROSLAW
权利人:POLSKA AKADEMIA NAUK CENIRUM B
摘要:The process of the instant invention is drawn to the synthesis of modified P-chiral nucleotide analogues in the form of pure diastereomers possessing preselected configuration at the P-atom. Oligonucleotides prepared by the method of the invention containing P-chiral compounds have enhanced hybridization and transporting properties.

标题 :Method for the synthesis of pheromones
发明人：QUEVAL PIERRE; CAIJO FRÉDÉRIC; ROUEN MATHIEU; TRIPOTEAU FABIEN
权利人:DEMETA
摘要:The invention relates to a method for the synthesis of pheromones functionalised on one of the ends thereof and comprising at least two conjugated double bonds with a majority stereochemical configuration (E, Z). The reaction is carried out in two steps, comprising: (a) a metathesis reaction between a functionalised olefin and an unsaturated aldehyde, in the presence of at least one specific catalyst selected from the ruthenium complexes comprising a 1,3-diaryl-imidazolidin-2-yl ligand and a styrenyl ether ligand, and (b) the reaction of the product obtained in this way with a triphenylalkylphosphonium salt.

标题:Sulfur transfer reagents for oligonucleotide synthesis

摘要:The use of N-formamidino-5-amino-3H-1,2,4-dithiazole-3-thiones, 5-phenyl-3H-1,2,4-dithiazole-3-thiones, and derivatives thereof as novel, efficient sulfur-transfer reagents is disclosed. Sulfur transfer from these reagents to compounds containing a P(III) atom (e.g., triphenylphosphine, 5′-O-DMT-thymidine 2-cyanoethyl-(N,N-diisopropyl)phosphoramidite, and 5′-O-DMT-3′-O-levulinyl dithymidilyl 2-cyanoethyl phosphite), was studied in solution by 31 P NMR and HPLC. The sulfur transfer from title compounds was also studied in the solid-phase synthesis of oligonucleotide phosphorothioates by phosphoramidite methods. In this application, the efficiency of the sulfur transfer reaction for 2′-deoxyoligonucleotides was better than 99.5%. The novel sulfurizing agents are synthesized, at low cost, using simple chemical methods. As opposed to many sulfur transfer reagents known in the prior art such as 1,2-benzodithiol-3-one-1,1-dioxide (Beaucage reagent) and 5-ethoxy-3H-1,2,4-dithiazole-2-one (EDIT), the sulfurizing agents disclosed herein are highly stable in solution, which increases their practical and commercial value.
