摘要:The present invention provided a continuous flow process for the synthesis of phenylhydrazine salts and substituted phenylhydrazine salts. Diazotization, reduction, acidic hydrolysis and salifying with acids are innovatively integrated together. Using acidic liquids of aniline or substituted aniline, diazotization reagents, reductants and acids as raw materials, phenylhydrazine derivative salts is obtained through the synthesis process, which is a three-step continuous tandem reaction including diazotization, reduction, acidic hydrolysis and salifying. The described synthesis process is a kind of integrated solutions, which is carried out in an integrated reactor. The feed inlets of the integrated reactor are continuously filled with raw materials. In the integrated reactor, diazotization, reduction, acidic hydrolysis and salifying are carried out continuously and orderly, and phenylhydrazine salts or substituted phenylhydrazine salts is obtained in the outlet of the integrated reactor without interruption. The total reaction time is no more than 20 min.

标题:Dynamic and combinatorial synthesis of polymerase primers
发明人：BENNER STEVEN ALBERT
权利人:BENNER STEVEN ALBERT
摘要:This invention relates to the field of nucleic acid chemistry, more specifically to compositions of matter that are nucleic acid analogs, and processes that use them. Still more specifically, these compositions comprise two fragments of DNA-like molecules, each having one or more ends modified to carry a reactive group, where the reactive group on one fragment can form a transient covalent bond with the reactive group on the other under conditions of dynamic equilibrium to form a composite, where the composite can then bind to a target oligonucleotide, such as a DNA or RNA molecule. Most specifically, once the transient covalent bond forms, the composite serves as a primer for a template-directed polymerization using a DNA polymerase, an RNA polymerase, or a reverse transcriptase. Once incorporated, the epimerization causes the base pair to be destabilized, the duplex containing the epimerized nucleoside to likewise be destabilized, and the double strand to then disassociate. This leaves the template available to template the synthesis of another complementary oligonucleotide containing the epimerizing base.
