  摘要：

  新合成了6-氯-2-环己烯酮3、6和11以及5-氯-2-环戊烯酮15。用化合物3和15在烯烃的光环加成中获得的结果表明，通过在烯酮的α′-位用氯取代弗洛林，降低了氧杂环丁烷与环丁烷的产物比。在分子内的光环加成6中没有形成氧杂环丁烷。化合物11不光加成至烯烃中。新合成的2-氯-3-环己烯酮8和9它们在λ= 366 nm的光下也是光稳定的，但是戊烷中的π-π*激发（λ= 254 nm）导致形成4,4-二甲基环己酮（29）。

  A procedure for the α-chlorination or bromination of a number of α,β-unsaturated carbonyls, and the dichlorination or bromination of alkenes, is developed using bisacetoxyiodobenzene (BAIB) and the HCl or HBr salt of pyridine. The reaction proceeds in an acceptable to a good yield and has a broad substrate scope. The dibromination is also achieved using a chiral I[V] reagent, although little enantioselectivity

  使用双乙酰氧基碘苯（BAIB）和吡啶的HCl或HBr盐开发了多种α，β-不饱和羰基的α-氯化或溴化方法，以及烯烃的二氯化或溴化方法。反应以可接受的产率进行，并具有良好的收率，并且具有广泛的底物范围。尽管可以实现很少的对映选择性，但是也可以使用手性I [V]试剂实现二溴化。

  Mixtures of OXONE ® and hydrobromic acid or hydrochloric acid afford solutions of bromine or chlorine, respectively. α-Bromo- or α-chloro-α,β-unsaturated carbonyl compounds were prepared by addition of hydrobromic acid or hydrochloric acid to the mixture of α,β-unsaturated carbonyl compounds and OXONE ® in CH2Cl2 followed by treatment of Et3N in moderate to good yields.

  Nuclear factor erythroid 2-related factor 2 (Nrf2) is a master regulator that promotes the transcription of cytoprotective genes in response to oxidative/electrophilic stress. Various Michael-type compounds were designed and synthesized, and their potency to activate the Keap1/Nrf2/ARE pathway was evaluated. Compounds bearing two Michael-type acceptors proved to be the most active. Tether length and rigidity between the acceptors was crucial. This study will help to understand how this feature disrupts the interaction between Keap1 and Nrf2.
