Time Dependent Density Functional Theory (TD-DFT) has been used to assist the design and synthesis of a series thioxanthone triplet sensitizers. Calculated energies of the triplet excitedstate (ET) informed both the type and position of auxochromes placed on the thioxanthone core, enabling fine-tuning of the UV-Vis absorptions and associated triplet energies. The calculated results were highly consistent

We utilized synthetic photochemistry to generate novel sp3-rich scaffolds and report the design, synthesis, and biological testing of a diverse series of amides based on the 1-(amino-methyl)-2-benzyl-2-aza-bicyclo[2.1.1]hexane scaffold. Preliminary antimalarial screening of the library provided promising compounds with activity in the 1–5 μM range with an enhanced hit rate. Further evaluation (solubility

Successful nucleophilic substitution at a methylene attached to the bridgehead (1-) position of the 2-azabicyclo[2.1.1]hexanering system opens the way to construction of novel derivatives having a wider range of functional groups attached to the 1-position via a methylene "spacer" (including the beta-amino acid homologue of 2,4-methanoproline) and provides access to epibatidine analogues containing
