We herein present a flexible approach for the incorporation of CF3 units into a predefined site of electron-rich alkenes that exploits the regiocontrolled introduction of an iodine handle and subsequent trifluoromethylation of the C(sp2)–I bond using fluoroform-derived “ligandless” CuCF3. The broad substrate scope and functional group tolerance together with the scalability and purity of the resulting

This invention relates to the field of nucleic acid chemistry, more specifically to the field of compositions of matter that comprise triphosphates of modified 2'-deoxynucleosides and oligonucleotides that are formed when these are appended to the 3'-end of a primer, wherein said modifications comprise NH2 moiety attached to their 3'-hydroxyl group and a fluorescent species in a form of a tag affixed to the nucleobase via a linker that can be cleaved. Such compositions and their associated processes enable and improve the sequencing of oligonucleotides using a strategy of cyclic reversible termination, as outlined in US Patent 6,664,079. Most specifically, the invention concerns compositions of matter that are 5'-triphosphates of ribo- and 2'- deoxyribonucleosides carrying detectable tags and oligonucleotides that might be derived from them. The invention also concerns processes wherein a DNA polymerase, RNA polymerase, or reverse transcriptase synthesizes said oligonucleotides via addition of said triphosphates to a primer.

There are disclosed compositions and methods to render nucleic acids resistant to nuclease digestion while maintaining sequence selective hybridization competency. The approach relies on utilizing nucleic acids as the polar head group of a nucleic acid-polymer amphiphile in order to assemble well-defined, discrete micellar nanoparticles. Dense packing of nucleic acid in the micelle corona allows for hybridization of complementary oligonucleotides while prohibiting enzymatic degradation.
