    The First In(OTf)3-Catalyzed Conversion of Kinetically Formed Homoallylic Alcohols into the Thermodynamically Preferred Regioisomers: Application to the Synthesis of 22α-Sterols
    摘要:
    A retro-ene reaction that generates the parent aldehyde and a sigmatropic rearrangement are involved in the In(OTf)3 -catalyzed conversion of homoallylic alcohols 1 into the thermodynamically favored regioisomers 2. This method can be used for the stereocontrolled synthesis of linear homoallylic 22α-sterols from their readily accessible branched 22β isomers.

    An operationally simple one‐jar one‐step mechanochemical Reformatsky reaction using in situ generated organozinc intermediates under neat grinding conditions has been developed. Notable features of this reaction protocol are that it requires no solvent, no inert gases, and no pre‐activation of the bulk zinc source. The developed process is demonstrated to have good substrate scope (39–82 % yield) and
    已开发出一种在简单研磨条件下使用原位生成的有机锌中间体进行的简单操作的一罐式一步机械化学Reformatsky反应。该反应规程的显着特征是它不需要溶剂,不需要惰性气体并且无需预先激活大量的锌源。事实证明,开发的工艺具有良好的底物范围(39-82%的产率),并且不管锌源的初始形态如何都有效。

    It is found that nanometer-sized bismuth mediates the allylation of carbonyl compounds in water to afford the corresponding homoallylic alcohol in high yields. Nanometer-sized bismuth is much more effective than regular bismuth powder in this reaction.

    A novel mediator (Al/KF) has been developed and employed in the Barbier‐type alkylations of various aldehydes and ketones with alkyl halide in water. The carbonyl compounds could be effectively converted into corresponding homoallylic alcohol in good yields only when allyl bromides or substituted allyl bromides were used as halides. Aromatic aldehydes could afford homoallylic alcohols in high yields
    已经开发了一种新型介体(Al / KF),并将其用于水中烷基卤与各种醛和酮的Barbier型烷基化。仅当使用烯丙基溴或取代的烯丙基溴作为卤化物时,羰基化合物才能有效地有效地转化为相应的均丙醇。芳香醛可以提供高收率的均丙醇,但不幸的是,在相同条件下,被硝基或氨基取代的芳香醛的烯丙基化不能顺利进行,酮和脂肪族羰基化合物的烯丙基化产率较低。还研究了反应的非对映选择性和区域选择性,主要产物优先选择赤型或反型异构体。通过使用Al / KF介导的苯甲醛与肉桂酸溴化物和4-溴-2-丁烯酸乙酯的水溶液进行γ加合物。

    from aldehydes via the usual reaction with common allylic metals 1, were converted to the corresponding α-adducts 6 by an acid-catalyzed allyl-transfer reaction. In the allyl-transfer reaction, anti- and syn-γ-adducts 3 gave E- and Z-α-adducts 6, respectively, and the optical purity of the γ-adducts 3 was transferred to the α-adducts 6 with >98%ee. This suggests that the allyl-transfer reaction proceeds
    高烯丙基醇 3 的 γ-加合物通过与常见烯丙基金属 1 的通常反应从醛衍生,通过酸催化的烯丙基转移反应转化为相应的 α-加合物 6。在烯丙基转移反应中,反-和顺-γ-加合物3分别得到E-和Z-α-加合物6,γ-加合物3的光学纯度转移到α-加合物6,>98 %ee。这表明烯丙基转移反应通过六元环状过渡态 [T] 立体选择性地进行。该反应由各种金属三氟甲磺酸盐以及路易斯酸和布朗斯台德酸催化。
