  A modular, selective approach to complex α-tertiary substituted malononitriles is reported. The method takes advantage of β-ester-substituted α,α-dinitrile alkenes as highly reactive, chemoselective electrophiles for 1,4-additions with organometallic nucleophiles to produce functionally and sterically dense all-carbon quaternary centers. In the presence of a chiral ester auxiliary bearing an aromatic

  报道了一种复杂的α-叔取代丙二腈的模块化，选择性方法。该方法利用β-酯取代的α，α-二不饱和烯烃作为有机金属亲核试剂进行1,4-加成的高反应性，化学选择性亲电试剂，可产生功能上和空间上均密集的全碳四元中心。在带有芳香环的手性酯助剂的存在下，由于有利的阳离子-π相互作用，发生了1,4-加成，选择性好至极好。高度官能化的丙二腈代表了多种构建基块，可用于高效，高度选择性的5,5-二取代吡咯并嘧啶酮的合成。

  A diverse reactivity of diazo compounds with nitrosoarene in an oxygen-transfer process and a formal [2 + 2] cycloaddition is reported. Nitosoarene has been exploited as a mild oxygen source to oxidize an in situ generated carbene intermediate under visible-light irradiation. UV-light-mediated in situ generated ketenes react with nitosoarenes to deliver oxazetidine derivatives. These operationally

  报道了重氮化合物与亚硝基芳烃在氧转移过程和正式的 [2 + 2] 环加成反应中的多种反应性。Nitosoarene 已被用作温和的氧源，在可见光照射下氧化原位生成的卡宾中间体。紫外光介导的原位生成的烯酮与亚硝基芳烃反应以提供氧氮杂环丁烷衍生物。这些操作简单的过程举例说明了无过渡金属和无催化剂的协议，以提供结构多样的 α-酮酯或氧氮杂环丁烷。

  tetraalkylaluminates prepared via hydroalumination in THF of various vinyl compounds resulted in selective addition to the keto group of phenylglyoxylic acid (−) menthyl ester. Not only simple alkyl groups but also functionalized alkyl groups were added. By this way, a variety of α-substituted mandelic acid (−) menthyl esters were obtained with diastereomeric excesses close to 70%.
