摘要:This application discloses a novel process for the synthesis of himbacine analogs, as well as the compounds produced thereby. The synthesis proceeds by alternative routes including the cyclic ketal amide route, the chiral carbamate amide route, and the chiral carbamate ester route. The compounds produced thereby are useful as thrombin receptor antagonists. The chemistry disclosed herein is exemplified in the following synthesis sequence:

摘要:Methods for the preparation of inorganic nanoparticles capable of fluorescence, wherein the nanoparticles consist of a host material that comprises at least one dopant. The synthesis of the invention in organic solvents allows to gain a considerably higher yield compared to the prior art synthesis in water. All kinds of objects can advantageously be marked and reliably authenticated by using an automated method on the basis of a characteristic emission. Further, the size distribution of the prepared nanoparticles is nartower which renders a subsequent size-selected separation process superfluous.
