The reaction mass is treated with an aqueous solution of a strong organic acid or a mineral acid. After decomposition of the resulting carminomycin and Lewis acids reactive complex, the reaction mass is extracted using a water insoluble organic solvent. As a result, carminomycin is extracted as a base. Full Article
y Process for triphosphate oligonucleotide synthesis By www.freepatentsonline.com Published On :: Tue, 19 May 2015 08:00:00 EDT This invention relates to a process for preparing an oligonucleotide 5'-triphosphate. The process comprises the steps of: (a) synthesizing an oligonucleotide having a 5' hydroxyl moiety; (b) reacting the 5' hydroxyl moiety with a reagent of formula I: to convert the 5' hydroxyl moiety to a 5'-H-phosphonate, wherein R1 and R2 are each independently selected from the group consisting of haloalkyl, aryl, substituted aryl, heteroaryl, substituted heteroaryl, cycloalkyl, substituted cycloalkyl, heterocycle, and substituted heterocycle, acyl, phosphoryl, substituted alkyl acyl, substituted heteroalkyl acyl, substituted aryl acyl or substituted heteroaryl acyl, substituted alkyl phosphoryl, substituted heteroalkyl acyl, substituted aryl phosphoryl, and substituted heteroaryl phosphoryl; (c) activating the H-phosphonate of step (b) by reacting the H-phosphonate with a silylating agent, a halogenated oxidizing agent, a nitrogen-containing heteroaryl, or a combination thereof, to form an activated H-phosphonate; and (d) treating the oligonucleotide having an activated H-phosphonate from step (c) with a poly(alkylammonium)pyrophosphate.
