Vacuum ultraviolet photoionization and ionic fragmentation of the isoxazole molecules

The photofragmentation of the isoxazole molecules producing ionized atomic and molecular fragments was investigated in the photon energy range of 9?32 eV, using synchrotron radiation excitation combined with ion time-of-flight spectrometry. Twenty-one well resolved cations were identified in the mass spectra of the isoxazole, and their appearance energies were determined. The yield curves of these cations were obtained in the photon energy ranges from their appearance energies up to 32 eV. Moreover, the total ion yield of isoxazole was recorded with high precision in the photon energy range of 9.9?10.5 eV. This allowed the determination of the adiabatic ionization energy of 9.96 (0.02) eV in excellent agreement with earlier spectroscopic studies. Our results show that the dissociative ionization of isoxazole starts from the ring-opening and isomerization of isoxazole, and further it follows strictly through its ionic states. Possible ionic fragmentation channels yielding particular ions are discussed.

Determination of long-range scalar 1H-1H coupling constants responsible for polarization transfer in SABRE

SABRE (Signal Amplification By Reversible Exchange) nuclear spin hyperpolarization method can provide strongly enhanced NMR signals as a result of the reversible association of small molecules with para-hydrogen (p-H2) at an iridium metal complex. The conversion of p-H2 singlet order to enhanced substrate proton magnetization within such complex is driven by the scalar coupling interactions between the p-H2 derived hydrides and substrate nuclear spins. In the present study these long-range homonuclear couplings are experimentally determined for several SABRE substrates using an NMR pulse sequence for coherent hyperpolarization transfer at high magnetic field. Pyridine and pyrazine derivatives appear to have a similar ?1.2 Hz 4J coupling to p-H2 derived hydrides for their ortho protons, and a much lower 5J coupling for their meta protons. Interestingly, the 4J hydride-substrate coupling for five-membered N-heterocyclic substrates is well below 1 Hz.

Donor-Acceptor Styrylisoxazoles: Solvatochromism and Large First Hyperpolarizability

The present work describes the synthesis and linear as well as nonlinear optical studies of donor-acceptor based styrylisoxazoles. Six styrylisoxazoles were synthesized, and examination of their photophysical properties reveals strong solvent polarity sensitivity due to intramolecular charge transfer characteristics. Most interestingly, we have measured large first hyperpolarizability (beta) values for these styrylisoxazoles. The largest beta value calculated was for the compound that bears the dimethylamine group as the donating moiety. Our current results suggest that a careful selection of the donor and acceptor groups can potentially lead to unprecedented enhancement of the (beta) values of isoxazole derivatives.

Discovery of pyrazolo[1,5-a]pyrimidine-based CHK1 inhibitors: A template-based approach – Part 2

Previous efforts by our group have established pyrazolo[1,5-a]pyrimidine as a viable core for the development of potent and selective CDK inhibitors. As part of an effort to utilize the pyrazolo[1,5-a]pyrimidine core as a template for the design and synthesis of potent and selective kinase inhibitors, we focused on a key regulator in the cell cycle progression, CHK1. Continued SAR development of the pyrazolo[1,5-a]pyrimidine core at the C5 and C6 positions, in conjunction with previously disclosed SAR at the C3 and C7 positions, led to the discovery of potent and selective CHK1 inhibitors.

The development of the solid-phase version of the modified Madelung indole synthesis is reported. The chemistry was initiated with the reductive amination of Bal resin using an ortho substituted aniline. The resin bound aniline was acylated with a variety of acid chlorides followed by cyclization with base to provide the desired indole after TFA-promoted cleavage from the resin.
