- An investigation towards the diastereoselective synthesis of 3-acetoxy/methoxy/phthalimido-β-lactams using chiral imines
-
The efficient diastereoselective synthesis of 3-acetoxy/methoxy/phthalimido-β-lactams 2/2′, 3/3′ and 4/4′ respectively was performed using chiral imines 1 obtained from chiral amines. Factors (solvent, temperature, substituent, steric bulk) influencing th

- Asymmetric induction in the addition of enantiomerically pure H-phosphinate to chiral aldimines: diastereoselective generation of α-amino phosphinates with P,C-stereogenic centers
-
α-Amino phosphinates with P,C-stereogenic centers were prepared from a P-retained addition of (RP)-(?)-menthyl H-phenylphosphinate to (R)-aldimines with up to 86:14 dr under catalyst and solvent free condition at ambient temperature; the single

- [3+2]-cycloaddition reaction between chiral oxaziridines and nitriles: Enantioselective synthesis of 2,3-dihydro-1,2,4-oxadiazoles
-
Enantiomerically pure 2,3-dihydro-1,2,4-oxadiazoles were synthesized by a cycloaddition reaction between chiral oxaziridines and nitriles. Assignment of absolute configurations was made by X-ray diffraction analysis, NOESY spectra, and theoretical calculations. Georg Thieme Verlag Stuttgart - New York.

- Chiral oxaziridines in the enantioselective synthesis of isoxazolidines

The stereoselective synthesis of oxaziridines with three stereogenic centres is presented in this paper. The chirality is provided by asymmetric induction, and a possible mechanism for the induced stereoselectivity is also discussed. These small heterocyc
