This invention is directed to, inter alia, compounds, methods, systems, and compositions for the maintenance, enhancement, and expansion of hematopoietic stem cells derived from one or more sources of CD34+ cells. Sources of CDS 4+ cells include bone marrow, cord blood, mobilized peripheral blood, and non-mobilized peripheral blood. Also provided herein are compounds of Formula I which are useful in maintaining, enhancing, and expanding of hematopoietic stem cells.

A nitrogen iodine exchange protocol of diaryliodonium salts with sodium azide salt is developed for general construction of significant functional acridines and carbazoles, in which introduction of nitrogen at a late stage was successfully established avoiding heteroatom incompatibility. Inorganic sodium azide served as the sole nitrogen atom source in this transformation. The diversiform functional acridines and carbazoles were comprehensively achieved through annulated diaryliodonium salts, respectively. Notably, Acridine orange (a fluorescent indicator for cell lysosomal dye) and Carprofen (a non steroidal anti-inflammatory drug) were efficiently established through this protocol.

A palladium-catalyzed regioselective C-H bond functionalization driven by CO as the stoichiometric reductant is described. Nitrogen heterocycles, e.g., carbazoles, are accessible in good to excellent yields with use of palladium acetate and 70 psig of carbon monoxide at 140 degreesC.
