Provided herein are compounds and methods for modulating abnormal repeat expansions of gene sequences. More particularly, provided are dimeric inhibitors of RNA and the uses of such inhibitors in regulating nucleotide repeat expansions, e.g., to treat Myotonic Dystrophy Type 1 (DM1), Myotonic Dystrophy Type 2 (DM2), Fuchs dystrophy, Huntington Disease, Amyotrophic Lateral Sclerosis, or Frontotemporal Dementia.
A general and convenient copper-mediated trifluoromethylthiolation of primary and secondary alkyl halides was described. Variation of the solvent, additives and time allowed optimization of the reaction. A wide range of alkyl halides were explored to give a set of alkyl trifluoromethyl thioethers in moderate to excellent yields. A variety of functional groups, including ethers, thioether, esters, nitriles, amides, and ketal groups, were well tolerated in the electrophilic partner.
Reported herein is a novel visible‐light photoredox system with Pd(PPh3)4 as the sole catalyst for the realization of the first direct cross‐coupling of C(sp3)−H bonds in N‐aryl tetrahydroisoquinolines with unactivated alkyl bromides. Moreover, intra‐ and intermolecular alkylations of heteroarenes were also developed under mild reaction conditions. A variety of tertiary, secondary, and primary alkyl
The present invention relates generally to selected fused pyrrolocarbazoles, including pharmaceutical compositions thereof and methods of treating diseases therewith. The present invention is also directed to intermediates and processes for making these fused pyrrolocarbazoles.
desired reductive alkylation of 2-thienyldialkylacetonitriles, a much lower temperature such as -100 ˚C was required. Also with these substrates, an interesting ring-opening/S-alkylation process was observed when the reductive alkylation were performed at -78 ˚C to give 1-alkylsulfanyl-1,3,4-trienes. A mechanistic discussion is given for this observation. reductive alkylation -reductiveaddition- reductive
