Provided are amine derivative compounds, pharmaceutical compositions thereof, and methods of treating ophthalmic diseases and disorders, such as age-related macular degeneration and Stargardt's Disease, using said compounds and compositions.
time. This protocol, merging visiblelight photoredox and palladium catalysis, provides a direct approach to conjugated tertiary allylic alcohol derivatives with broad functional group tolerance in moderate to excellent yields. Mechanistic studies suggest that, although two possible pathways exist in the transformation, radical oxyalkenylation promoted by visiblelight photoredox takes over the major

indoles excellent ee values were obtained (up to 98 % ee). The versatility of the propargylic amines obtained was demonstrated by their further elaboration to formaltotalsyntheses of the antibiotic (+)‐anisomycin and the cytokine modulator (−)‐cytoxazone.

Despite their enormous synthetic relevance, the use of polar organolithium and Grignardreagents is greatly limited by their requirements of low temperatures in order to control their reactivity as well as the need of dry organic solvents and inert atmosphere protocols to avoid their fast decomposition. Breaking new ground on the applications of these commodity organometallics in synthesis under more

N-Propargylanabasine derivatives bearing various substituents at the carbon atom of the alkyne fragment were obtained by the reaction of anabasine hydrochloride with terminal alkynes and paraformaldehyde. The reaction proceeded with retention of the C(2) chiral center in anabasine fragment. The by-products of the reaction, including 1,3-diacetylene (the products of dimerization of alkynes) and conjugated
