Synthesis of 2-substituted pyrrolidines from nitriles
摘要:
A novel and synthetically facile production of 2-substituted pyrrolidines from commercially available nitriles is reported herein. This methodology is operationally simple, and only requires the use of an extraction and a single chromatographic purification to furnish the title compounds in high purity and very good yields.

A designed Tf2O-promoted intramolecular Schmidt reaction of 2-substituted ω-azido carboxylicacids was demonstrated. Tf2O was used as an activation reagent for the carboxylicacid, and ω-azido anhydride was in situ generated, releasing a molecular TfOH, which acted as an acid promoter for the Schmidt process. A series of 2-substituted pyrrolidines was produced and acetylated for better purification
The present invention is directed to compounds of formula (I),
and pharmaceutically acceptable salts and solvates thereof, their synthesis, and their use as HSP-90 inhibitors.

The strong boron Lewis acid B(C6F5)3 in combination with phenylsilane enables the regioselective cleavage of one out of two or three carbon–nitrogen bonds in cyclic secondary and tertiary amines, respectively. This amine deconstruction extends to large saturated nitrogen-containing heterocycles, and the functional-group tolerance is good.
