Part I: Synthetic studies toward the southern portion of Azaspiracid-1; Part II: Total synthesis of amphidinolide B₁ and the proposed structure of amphidinolide B₂

Creator:: Lu, Liang
Abstract:: The structural architecture present in marine toxin azaspiracid - 20 stereocenters, 9 rings, 3 separated spirocenters - has attracted considerable synthetic attention. Our efforts toward the synthesis of azaspiracid have led to the completion of both C₁-C₂₆ northern and C₂₇-C₄₀ southern halves. Herein, the synthesis of southern FGHI ring system...

Investigating Low-Frequency Vibrations in Condensed Matter Using Time-Resolved Third-Harmonic Generation Spectroscopy

Creator:: Wang, Liang
Abstract:: In this thesis, I present a new method we developed to study low frequency (< 700 cm⁻¹) vibrational dynamics: Time-resolved third-harmonic generation (TRTHG) spectroscopy. Among a variety of vibrational spectroscopy techniques, TRTHG differentiates itself with robustness, versatility, and simplicity. In TRTHG experiment, that involves only two ultrashort laser pulses, the...

Tracking Excited State Proton Transfer and Inhibition with Ultrafast Raman and Transient Absorption Spectroscopy

Creator:: Oscar, Breland G.
Abstract:: In this dissertation, excited state proton transfer (ESPT) and its inhibition in solution and protein environments are revealed using both femtosecond transient absorption (fs-TA) spectroscopy and femtosecond stimulated Raman spectroscopy (FSRS). Using a tunable Raman pump to enhance transient vibrational features of the photoacidic chromophore HPTS in methanol and methanol...
