标题 :Synthesis of 5-Beta-Keto-1,2,4-Oxadiazoles and Conversion of 5-Beta-Keto-1,2,4 Oxadiazoles to N-Pyrazolyl Amidoximes

摘要:The disclosed invention relates to a process for preparing 5-β-keto-1,2,4-oxadiazoles of formula (I), and conversion of 5-β-keto-1,2,4-oxadiazoles (I) into N-pyrazolyl amidoximes of the formula (II) through reaction with hydrazine. The process is defined by two steps. An amidoxime, which may be prepared in situ, is condensed with a β-keto ester to form a 5-β-keto-1,2,4-oxadiazole. The 5-β-keto-1,2,4-oxadiazole is subsequently reacted with hydrazine to furnish the desired N-pyrazolyl amidoxime. The disclosed invention provides several advantages over the current state of the art for the synthesis of N-pyrazolyl amidoximes, which require the condensation of a pyrzolylamine with an actived substrate and subsequent reaction with hydroxyl amine. N-pyrazolyl amidoximes are useful synthetic intermediates, especially for the preparation of photographic developing chemicals.

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.
