  • Synthesis of enantiopure 1,2-azido and 1,2-amino alcohols via regio- and stereoselective ring-opening of enantiopure epoxides by sodium azide in hot water

    日期:2016.2
    A practical and convenient method for the efficient and regio- and stereoselective ring-opening of enantiopure monosubstituted epoxides by sodium azide under hydrolytic conditions is reported. The ring-opening of enantiopure styryl and pyridyl (S)-epoxides by N3 - in hot water takes place preferentially at the internal position with complete inversion of configuration to produce (R)-2-azido ethanols
    报道了一种实用且方便的方法,用于在水解条件下通过叠氮化钠对映体纯单取代环氧化物进行有效的区域和立体选择性开环。对映体纯苯乙烯基和吡啶基 (S)-环氧化物在热水中通过 N3 - 开环优先在内部位置发生,构型完全反转,生成对映体含量高达 99% 的 (R)-2-叠氮基乙醇区域选择性,而(S)-金刚烷基环氧乙烷主要以优异的收率提供(S)-1-金刚烷基-2-叠氮基乙醇。一般来说,通过在水/THF中用PPh3还原手性1,2-叠氮基乙醇,可以高收率和优异对映体纯度获得1,2-氨基乙醇,然后转化为Boc或乙酰胺衍生物。

  • Asymmetric aminohydroxylation of substituted styrenes: applications in the synthesis of enantiomerically enriched arylglycinols and a diamine
    作者:Peter O’Brien、Simon A. Osborne、Daniel D. Parker
    DOI:10.1039/a803821j
    日期:——
    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。
