The present disclosure provides compounds of Formula (I): and pharmaceutically acceptable salts, solvates, hydrates, polymorphs, co-crystals, tautomers, stereoisomers, isotopically labeled compounds, and prodrugs thereof. The provided compounds may be tumor necrosis factor ("TNF") receptor associated protein 1 ("TRAP1") modulators (e.g., TRAP1 activators). The provided compounds may also rescue the activity in PTEN-induced kinase 1 ("PINK1") loss of function contexts. The provided compounds may also improve mitochondrial health, function, quality, quantity, and/or activity, and/or reduce the production of reactive oxygen species. The provided compounds may also refold or solubilize aggregated or misfolded proteins such as α-synuclein. The present disclosure also provides pharmaceutical compositions comprising the provided compounds; kits comprising the provided compounds or pharmaceutical compositions; and methods of using the provided compounds and pharmaceutical compositions (e.g., for treating a disease in a subject in need thereof).

日期:2000.3.1
[reaction: see text] The synthesis of the C1-C13 fragment 3 of leucascandrolide A has been completed utilizing a stereoselective and regioselective reductive cleavage of a highly functionalized spiroketal to incorporate the cis-2,6-disubstituted tetrahydropyan. The spiroketal was constructed by addition of a lithiated pyrone 5 to aldehyde 6.

A general and highlyenantioselective synthesis of oxygen heterocycles from readily available in situ generated pyrylium derivatives has been realized by embracing a multi-coordination approach with helical anion-binding tetrakistriazole catalysts. The high activity of the tetrakistriazole (TetraTri) catalysts, with distinct confined anion-binding pockets, allows for remarkably low catalyst loadings
