Paragraph 001072-001074, (2019/06/05)
Provided herein are compounds and methods for modulating abnormal repeat expansions of gene sequences. More particularly, provided are 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.
Vapor phase phototransposition chemistry of dimethylpyrazines and dimethylpyrimidines

, p. 216 - 228 (2017/11/17)
Based on their phototransposition chemistry, the three dimethylpyrazines and four dimethylpyrimidines can be arranged into two groups. 2,5-Dimethylpyrazine, 2,5-dimethylpyrimidine, and 4,6-dimethylpyrimidine constitute a photochemical triad. Irradiation of any one member of the triad in the vapor phase results in the formation of the other two members. The other four isomers, 2,6-dimethylpyrazine, 2,3-dimethylpyrazine, 2,4- dimethylpyrimidine, and 4,5-dimethylpyrimidine constitute a photochemical tetrad. Irradiation of any one member results in the formation of the other three. In addition, 2,4-dimethylpyrimidine and 2,6-dimethylpyrazine also photoisomerize to 3,6-dimethylpyridazine. Irradiation of the last in the vapor state resulted in the four members of the tetrad.

Alkyne-1,4-diols are readily available substrates which are isomerised to 1,4-diketones using Ru(PPh3)3(CO)H2/xantphos as a catalyst. In situ cyclisation into furans, pyrroles and pyridazines has been achieved under suitable conditions.
Synthesis and structure of dilead(II) and dimanganese(II) complexes of macrocycles derived from 3,6-diformylpyridazine
Brooker, Sally,Kelly, Robert J.
, p. 2117 - 2122 (2007/10/03)
An improved synthesis of 3,6-diformylpyridazine I has been elaborated. The macrocyclic complexes Pb2L1(ClO4)4 1 and [Pb2L2][ClO4]4 2 were prepared from this precursor, 1,3-diaminopropane and lead(II) perchlorate in 1:1:1 and 2:2:1 ratios respectively. The ability of lead(II) perchlorate to template the formation of the two macrocycle ring sizes, L1 = (2 + 2) and L2 = (4 + 4), simply by alteration of the reagent ratio is unprecedented. Transmetallation of 1 or 2 with manganese(II) perchlorate and an excess of sodium thiocyanate led to the formation of [Mn2L1(NCS)4] 3. Single-crystal X-ray analyses of 2 and 3 revealed that on transmetallation a ring contraction, (4 + 4) to (2 + 2), occurs. The two manganese(II) ions have irregular geometries and are inequivalent; one is six- whilst the other is seven-co-ordinate. Unusual single-atom > NCS bridging of the manganese ions occurs.
