  • Unusual solvent-effect in stereochemistry of asymmetric epoxidation using a (salen)chromium(III) complex as a catalyst
    作者:Hirotoshi Imanishi、Tsutomu Katsuki
    DOI:10.1016/s0040-4039(96)02274-5
    日期:1997.1
    Epoxidation of conjugated olefins has been examined with (salen)chromium(III) complexes as catalysts. Although (salen)chromium(III) complexes were catalytically less active than the corresponding (salen)manganese(III) complexes, the reactions with the chromium complexes were found to exhibit interesting solvent-dependent stereochemistry.
    已经用(salen)铬(III)配合物作为催化剂检查了共轭烯烃的环氧化。尽管(salen)铬(III)配合物的催化活性低于相应的(salen)锰(III)配合物,但发现与铬配合物的反应表现出有趣的溶剂依赖性立体化学。
  • Synthesis and antihypertensive activity of substituted trans-4-amino-3,4-dihydro-2,2-dimethyl-2H-1-benzopyran-3-ols

    position. Exceptions to this were the 7-nitro-4-pyrrolidine analogue and the 6-nitro-3-chloropropylamine, which retained marked antihypertensive activity. All of these compounds were direct vasodilators and had comparable antihypertensive activity to hydralazine and to the calcium antagonist, nifedipine. The synthetic route to these compounds involves cyclization of of propargyl ethers to 2H-1-benzopyrans
    制备了一系列新型取代的反式-4-氨基-3,4-二氢-2,2-二甲基-2H-1-苯并吡喃-3-醇,并在有意识的乙酸脱氧皮质酮(DOCA)/盐水处理中测试了其降压活性。高血压大鼠。最佳的降血压活性需要一个强的吸电子基团与6位上的吡咯烷基或哌啶子基团一起进行6位取代。7-硝基-4-吡咯烷类似物和6-硝基-3-氯丙胺的例外,它们保留了明显的降压活性。所有这些化合物都是直接的血管扩张药,并且具有与肼屈嗪和钙拮抗剂硝苯地平相当的降压活性。这些化合物的合成路线包括将炔丙基醚环化为2H-1-苯并吡喃,然后通过溴代醇转化为3,4-环氧化物,用适当的胺开环。间取代的炔丙基醚在热环化反应中同时产生5-和7-取代的苯并吡喃,前者占优势。描述了一种新的制备2,2-二甲基-7-硝基苯并吡喃的途径。

    High enantioselectivity and good chemical yields were realized in the epoxidation of 2,2-dimethylchromene derivatives using achiral (salen)manganese(III) complex 5 as a catalyst in the presence of axially chiral bipyridine N,N′-dioxide 4.

    日期:1994.3
    Asymmetric oxidation of sulfides was examined by using (salen)manganese(III) complexes as catalysts and (8S,8′S,1″S,2″S)-complex (3b) was found to show high asymmetric induction up to 90% ee. To be interested, however, (8R,8′R,1″S,2″S)-complex (1a) that showed excellent asymmetric induction in the epoxidation of simple olefins was a poor catalyst for the oxidation of sulfides.
