摘要:The present invention is the method for incorporation of acetal and acetal ester groups for protection of hydroxyl function. The method is applied in particular in the processes of RNA synthesis. The method can be employed in the synthesis of nucleosides with acetal and acetal ester groups for the protection of hydroxyl functions. The method according to the invention consists of the reaction of an organic compound containing at least one hydroxyl group, soluble in an aprotic solvent, with a compound of the general formula 1, R 1 -S-CH 2 -O-R 2 (1) in the presence of SnCl 4 , in an aprotic solvent. In the second aspect, the present invention is the method of protecting the hydroxyl function, particularly in position 2', in nucleoside derivatives, based on the incorporation of an acetal or acetal ester group.

摘要:The present invention provides biomimetic compounds and libraries thereof, as well as methods for their production. In general, the inventive method involves the selection of a desired biological synthetic pathway and mimics that synthetic pathway utilizing modern synthetic tools. The structures formed from this method are preferably generated in fewer than four steps. These scaffold structures can then be functionalized to yield biomimetic compounds and libraries of compounds. In preferred embodiments, biomimetic compounds and libraries are generated from an oxidative phenolic coupling reaction. In other particularly preferred embodiments, the compounds and libraries of compounds are generated from cascade reactions to yield bicyclo [n. 3.1 ] ring systems, medium ring systems, and fused ring systems. In addition to compounds, libraries and methods for their production, the present invention also provides pharmaceutical compositions and methods and kits for determining one or more biological activities of the library members.

摘要:A catalyst system includes a metallocene compound having the formula R 9 L 1 L 2 M 1 R 1 R 2 wherein R 9 is a bridge between ligands L 1 and L 2 and M 1 is a metal of Group IVB of the Periodic Table such as titanium, zirconium and hafnium and R 1 and R 2 can be hydrogen or aliphatic or aromatic groups. Bridge R 9 can include silicon, germanium or tin. The metallocene compound of the invention as synthesized has a racemic to meso isomer ratio of greater than 5 to 1, thereby precluding the need for subsequent separation of the meso isomer.
