Whole-cell yeast-mediated preparation of (R)-2-chloro-1-(3-nitrophenyl) ethanol as a synthetic precursor for (R)-phenylephrine
Tokoshima, Daisuke,Hanaya, Kengo,Shoji, Mitsuru,Sugai, Takeshi
, p. 95 - 99 (2013/10/01)
The incubated whole-cell biocatalyst of Pichia minuta JCM 3622 reduced 2-chloro-1-(3-nitrophenyl)ethanone to provide (R)-2-chloro-1-(3-nitrophenyl) ethanol with 99.2% ee in 87% isolated yield in the presence of Amberlite XAD-7 as a reservoir for the hydrophobic, crystalline and toxic substrate. The product was transformed to (R)-1-(3-hydroxyphenyl)-2-methylaminoethanol (phenylephrine, 1a), a selective α1-adrenergic receptor agonist, in 98.0% ee over five steps.
Ozone-mediated Nitration of Aromatic Ketones and Related Compounds with Nitrogen Dioxide
Suzuki, Hitomi,Murashima, Takashi
, p. 903 - 908 (2007/10/02)
Alkyl aryl ketones react smoothly with nitrogen dioxide at low temperatures in the presence of ozone to give ortho- and meta-nitro derivatives as the principal products, the former usually being predominant (ortho:meta = 1.1-3.8:1.0).No attack was observed on the alkyl side chains.
