  medicinal chemistry and natural products. Herein, we report that an exceptionally simple and inexpensive FeII complex efficiently catalyzes the direct transformation of simple alkenes into unprotected amino alcohols in good yield and perfect regioselectivity. This new catalytic method was applied in the expedient synthesis of bioactive molecules and could be extended to aminoetherification.

  converted into various valuable blocks in organic and pharmaceutical synthesis. A diastereoselective β-halogenation of benzylic alcohols was achieved under simple and low-cost conditions, which provided a direct synthesis of β-halohydrins. The simple reaction conditions, easily available reagents, high diastereoselectivities, and additional oxidant-free make this reaction very attractive and practical

• Asymmetric aminohydroxylation of substituted styrenes: applications in the synthesis of enantiomerically enriched arylglycinols and a diamine

  The catalytic asymmetric aminohydroxylation of a variety of styrene derivatives and vinyl aromatics using osmium tetroxide in conjunction with alkaloid-derived ligands [e.g. (DHQ)2PHAL or (DHQD)2PHAL] and haloamine salts of alkyl carbamates (e.g. ethyl carbamate or tert-butyl carbamate) has been investigated. By observing the effect of different aromatic substituents and alkyl carbamates on the regioselectivity, yield and enantioselectivity of the aminohydroxylation reactions, a number of conclusions have been reached: (i) the 1-aryl-2-hydroxyethylamine regioisomers were obtained as the major products in reasonable yield and high (87%) enantiomeric excess; (ii) tert-butyl carbamate was superior to ethyl carbamate in terms of yield, enantioselectivity and ease of removal of the N-protecting group; (iii) high (96%) enantioselectivity was observed with a 4-methoxy-substituted styrene whereas ortho-substituted styrenes gave lower enantioselectivities; (iv) chiral ligands (DHQ)2PHAL and (DHQD)2PHAL gave essentially equal and opposite senses and degrees of asymmetric induction; (v) regioselectivity was ligand dependent with better regioselectivity (and therefore higher isolated yields) obtained with (DHQ)2PHAL than with (DHQD)2PHAL. The products of the aminohydroxylation reactions were used to prepare enantiomerically enriched arylglycinols and a chiral diamine.

  研究人员使用四氧化锇与生物碱衍生配体[如 (DHQ)2PHAL 或 (DHQD)2PHAL] 以及氨基甲酸烷基酯的卤胺盐（如氨基甲酸乙酯或氨基甲酸叔丁酯）共同催化多种苯乙烯衍生物和乙烯基芳烃的不对称氨基羟基化反应。通过观察不同芳香取代基和烷基氨基甲酸酯对氨基羟化反应的区域选择性、产率和对映选择性的影响，得出了一些结论：(i) 主要产物为 1-芳基-2-羟乙基胺，产率合理，对映体过量率高（87%）；(ii) 氨基甲酸叔丁酯在产率、对映体选择性和 N-保护基的易去除性方面优于氨基甲酸乙酯；(iii) 4-甲氧基取代苯乙烯的对映选择性高（96%），而正交取代苯乙烯的对映选择性较低；(iv) 手性配体(DHQ)2PHAL 和(DHQD)2PHAL 的不对称诱导作用和程度基本相同；(v) 区域选择性与配体有关，(DHQ)2PHAL 比 (DHQD)2PHAL 的区域选择性更好（因此分离产率更高）。氨基羟化反应的产物被用于制备对映体富集的芳基甘氨醇和手性二胺。

• An efficient reduction protocol for the synthesis of β-hydroxycarbamates from β-nitro alcohols in one pot: a facile synthesis of (−)-β-conhydrine

  An efficient and practical one-pot protocol for the reduction of beta-nitro alcohols to their corresponding N-(tert-butoxycarbonyl) amino alcohols using Zn-NH4Cl in aqueous methanol is described. Other reducible groups such as ketones and isolated double bonds remained intact. This methodology allows a short synthesis of (-)-beta-conhydrine to be achieved. (C) 2008 Elsevier Ltd.
