A highly enantioselective hydrogenation of cyclic imines for synthesis of chiral cyclic amines has been realized. With the complex of iridium and (R,R)-f-spiroPhos as the catalyst, a range of cyclic 2-aryl imines were smoothly hydrogenated under mild conditions without any additive to provide the corresponding chiral cyclic amines with excellent enantioselectivities of up to 98% ee. Moreover, this

The enantiospecific synthesis of a series of 2(S)-alkylpyrrolidines from 2-cyano oxazolopyrrolidine synthon is described. Two of the synthesised compounds represent key intermediates towards ozabicyclic alkaloids.

The title compounds have been prepared from 3-acylpropionic acids 2 and (-)-R-phenylglycinol in a three-step sequence in > 98% enantiomeric excess. The R group in 2 ultimately becomes the 2-substituent in the chiral pyrrolidine.

An efficient procedure for the preparation of the title compounds in high enantiomeric purity has been realized starting from 3-acylpropionic acids. Stereoselective reduction of chiral bicyclic lactams 2a-h, prepared from the corresponding gamma-keto acid and (R)-phenylglycinol, using alane or triethylsilane with titanium tetrachloride provided the N-substituted pyrrolidines and pyrrolidinones, respectively. Subsequent cleavage of the phenylglycinol returned the desired amines and lactams. The enantiomeric purity of these compounds was determined to be > 98% by chiral stationary-phase HPLC.
