nitric oxide synthase (iNOS). To our knowledge, only few methods have been reported for the synthesis of 4,5-dialkylsubstituted 2-imino-1,3-selenazolidine derivatives (2), which are the selenium analogue of 1. Herein, we report the directsynthesis of 2 from the corresponding O-methanesulfonyl β-aminoalcohol hydrochlorides using potassium selenocyanate and evaluation for the inhibitory activity against

Asymmetricreduction of α-oxoketoxime ethers with the reagents prepared in situ from trimethyl borate and chiral amino alcohols derived from either L-proline or α-pinene was investigated. Both cyclic and acyclic α-oxoketoxime ethers were reduced to afford the corresponding chiral 1,2-amino alcohols with high enantioselectivities.

An efficient three-step methodology developed for the preparation of 1,2-amino alcohols. In the first step a rapid coupling between bromoketones and potassium phthalimide in ionic liquid produced alpha-phthalimido ketones in quantitative yields, which is followed by a facile reduction using NaCNBH3 in acetic acid to give corresponding phthalimido alcohols and finally effecting hydrazinolysis in water at 60 degrees C to yield biologically important 1,2-amino alcohols.
