Practical syntheses of N-acetyl (E)-β-arylenamides
A facile and practical method for the preparation of (E)-β- arylenamides [(E)-N-(1-arylprop-1-en-2-yl]acetamides] has been developed by reductive acetylation of the corresponding oximes with iron(II) acetate as the reducing reagent. Employment of hexamethylphosphoramide as the solvent was found to be critical for the high E/Z selectivity. The methodology has been applied in efficient syntheses of a key chiral intermediate of tamsulosin by asymmetric hydrogenation. Georg Thieme Verlag Stuttgart . New York.

N-oxygenation of amphetamine and methamphetamine by the human flavin- containing monooxygenase (form 3): Role in bioactivation and detoxication
(+)- And (-)-amphetamine and methamphetamine were N-oxygenated by the cDNA expressed adult human flavin-containing monooxygenase form 3 (FMO3), their corresponding hydroxylamines. Two major polymorphic forms of human FMO3 were studied, and the results sug

STANNOUS CHLORIDE REDUCTION OF α,β-UNSATURATED NITROALKENES : A DIRECT SYNTHESIS OF 2-ARYL-2H-1-BENZOPYRAN-3(4H)-ONE OXIMES
Stannous chloride, in acetone, readily reduced the α,β-unsaturated nitroalkenes to the cprresponding oximes at the room temperature.A series of 2-aryl-3-chromanone oximes were obtained via the reduction of 3-nitrochromenes.
