  Asymmetric Iodolactonization Utilizing Chiral Squaramides

  摘要：

  Asymmetric iodolactonization of gamma- and delta-unsaturated carboxylic acids has been explored in the presence of six different chiral organocatalysts 5-8. The catalyst 6b was found to facilitate the cyclization of 5-arylhex-5-enoic acids 1 to the corresponding iodolactones 2 with up to 96% ee. By this protocol, unsaturated carboxylic acids are converted enantioselectively to synthetically useful delta-lactones in high yields using commercially available NIS. Apparently, both hydrogen bonding and aryl/aryl interactions are important for efficient stereodifferentiation.

  A scalable and efficient electrocatalytic dehydrogenative esterification is reported. With an indirect electrolysis strategy, both intra- and intermolecular-type reactions were amenable to this practical method. With n-Bu4NI as the catalyst, undesired decarboxylation and Baeyer–Villiger oxidation were suppressed. More importantly, this novel method provided reliable and direct access to the natural

  据报道可扩展且有效的电催化脱氢酯化。通过间接电解策略，分子内和分子间反应都适合该实用方法。使用n -Bu 4 NI作为催化剂，可以抑制不希望的脱羧和Baeyer-Villiger氧化。更重要的是，这种新颖的方法可提供以克为单位的对天然产物胞嘧啶酮A的可靠，直接的获取。

  It′s the iodine: The intra‐ and intermolecular title reaction is catalyzed by an in situ generated ammonium (hypo)iodite species. Either H2O2 or tert‐butyl hydroperoxide (TBHP) can be used as an environmentally benign oxidant and a wide range of substrates react to give the corresponding α‐acyloxycarbonyl compounds in good to excellent yields.

  Highly enantiomerically enriched γ- and δ-lactams have been prepared by a simple and very efficient procedure that involves the asymmetric transfer hydrogenation of N-(tert-butylsulfinyl)iminoesters followed by desulfinylation of the nitrogen atom and spontaneous cyclization to the desired lactams during the basic workup procedure. Five- and six-membered ring lactams bearing aromatic, heteroaromatic

  高度对映体富集的γ-和δ-内酰胺是通过一种简单且非常有效的方法制备的，该方法包括N-（叔丁基亚磺酰基）亚氨基酸酯的不对称转移氢化，接着是氮原子的脱亚磺酰化，并在反应过程中自发环化为所需的内酰胺​​。基本的检查程序。已经以非常高的产率获得了带有芳族，杂芳族和脂族取代基的五元和六元环内酰胺，并且ee高达99％以上。稍加修改，即可制备出高收率和极高对映选择性的ε-内酰胺。通过改变亚磺酰基手性助剂的绝对构型，可以以相等的效率制备最终内酰胺的两种对映体。

  A novel enantioselective bromolactonization of α,β-unsaturated ketones using bifunctional amino-urea catalysts has been developed. The scope of the reaction is evidenced by 23 examples of halolactones bearing various functionalities with up to 99% yield and 99:1 er. Unlike typical urea catalysts that require electron-deficient substituents to enhance the hydrogen bond strength, it is interesting to
