ON THE CHEMISTRY OF 4-AMINO-THIAZOLINE-2-THIONES .2.

6-Amino-thiazolo[4,5-c]isothiazole derivatives 4 are obtained by addition of hydrogen sulfide to the 4-Amino-thiazoline-5-carbonitrile 2 followed by cyclooxidation of the intermediate thioamides 3. In the presence of sodium sulfite the hydrolysis of the 4-amino-2-methylthio-thiazolium salts 5 derived from the title compounds 1 yields the 4-amino-thiazolin-2-ones 6. By their further hydrolysis the 2,4-dioxo-thiazolidin-5-carboxamides 8 are formed. The 2-oxo-and 2-thioxo-thiazolo [4,5-d]pyrimidin-7-ones and -thiones available from 1 undergo ring opening by hydrolysis to give the substituted 4-amino-6-oxo- and 4-amino-6-thioxo-pyrimidine-5-thiols 15a-h and 13i-e. They have been isolated as their disulfides 14 or 5-alkyl derivatives i.e. the substituted 4-amino-5-alkylthiopyrimidin-6-ones and -thiones 16. In analogy, the intermediate 6-amino-7-oxo-thiazolo[4,5-d] pyrimidin-2-thione 18 and the 7-amino-thiazolo[4,5-d]-pyrimidin-2-thione 24 derived from 1 react by ring cleavage to yield the 1,4- and 4,6-diamino-pyrimidin-5-thiole derivatives 22 and 27, respectively, isolated as their disulfides or alkylthio-derivatives. From the pyrimidine 16b the pyrimido[5,4-b]1,4-thiazine derivative 18 can be obtained.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 700-12-9. Computed Properties of C11H16.

A new size-expanded RNA alphabet: Computational design of benzo-homologated (xtz-) isothiazole RNA and comparisons to the x-thieno RNA

Fluorescent nucleobase analogs are of great interest because of their widespread applications in nucleic acids research. In the present work, a new benzo-homologated RNA alphabet comprising xtzA, xtzG, xtzC, and xtzU was computationally designed based on the isomorphic tz-bases. The structural, electronic, and photophysical properties are studied by means of DFT and TDDFT calculations, and the effects of water solution, ribose, and base pairing on the singlet excited transitions were examined. The results are compared with those for tz-bases and xth-bases. These new base analogs can form stable Watson-Crick base pairs with natural counterparts as tz-bases and xth-bases do. Their ionization potentials and HOMO-LUMO gaps are in the middle of tz-bases and xth-bases: xth-base < xtz-base < tz-base. Furthermore, all xtz-bases are predicted to have smaller IPs and HOMO-LUMO gaps than natural bases and tz-bases, they are suggested to be candidates for applications in nanowire technology. The S-1 states for all xtz-bases are revealed to be pi pi* dominated by the configuration HOMO -> LUMO. In water solution, compared with tz- or xth-bases, the lowest pi pi* states are about 20.06-21.91 kcal/mol red-shifted or 0.92-4.15 kcal/mol blue-shifted, respectively. Linking to ribose has negligible effects on the S-1 excitation energies, but it owns a larger impact on the corresponding oscillator strengths. Base pairing and water solution as a whole has very little effects on the S-1 transition energies of xtzA and xtzC, but it will red-shift those for xtzG and xtzU by 6.69 and 5.30 kcal/mol, respectively. All xtz-bases are expected to display visible fluorescence with the wavelengths predicted to be 540, 585, 524, and 506 nm for xtzA, xtzG, xtzC and xtzU, respectively, in water solution. Though structurally very similar, the excitation maxima and fluorescence emissions of xtz- and xth-bases show distinct differences, allowing them to be distinguished from each other by their spectroscopic characters.

Electron attachment to the aza-derivatives of furan, pyrrole, and thiophene

The temporary anion states of gas-phase furan, isoxazole, oxazole, pyrrole, pyrazole, imidazole, thiophene, isothiazole, and thiazole are characterized by means of electron transmission spectroscopy. The measured energies of vertical electron attachment are compared with the virtual orbital energies of the neutral state molecules supplied by MP2 and B3LYP calculations with the 6-31G* basis set. The calculated energies, scaled with empirical equations, reproduce satisfactorily the experimental attachment energies. Replacement of a ring CH group with a nitrogen atom increases the electron-acceptor properties, although the stabilization of the pi* anion states is not as large as that of the pi cation states, in line with the bond length variations caused by aza-substitution. In the spectra of thiophene and isothiazole the first pi* resonances display sharp vibrational structure with energy spacing of about 80 meV. The spectrum of isothiazole presents clear evidence for a low-energy (1.61 eV) resonance ascribed to the lowest sigma* anion state.

Positively Charged Active Sites for the Adsorption of Five-Membered Heterocycles on Silver Colloids

The adsorption of isothiazole on silver colloids was studied by surface-enhanced Raman scattering (SERS) spectroscopy in comparison with other five-membered heterocycles. The experimental results coupled with those obtained by density functional theory calculations for molecule/metal complexes evidenced the presence of positively charged active sites on the surface of the silver nanoparticles, along with a close relation between ligand basicity and strong SERS effect.
