  Photochemical and acid-catalyzed dienone-phenol rearrangements. The effect of substituents on the regioselectivity of 1,4-sigmatropic rearrangements of the type A intermediate

  摘要：

  Birch reduction of isophthalic acid and 3-cyanobenzoic acid followed by (1) methylation of the resulting enolate with methyl iodide and (2) esterification with diazomethane provided 2-carbomethoxy- and 2-cyano-6-methyl-6-carbomethoxy-1,4-cyclohexadienes 9 and 25. Type A photorearrangements of a series of 2-carbomethoxy-, 2-cyano-, 2-methoxy-, and 2-methyl-4-carbomethoxy-4-methyl-2,5-cyclohexadien-1-ones 11, 26, 45a, and 45b gave 4-carbomethoxy-3-methyl-2-substituted-phenols 12, 28, 46, and 31. It has been demonstrated that the regioselectivity of type A photorearrangement of C(2) substituted 2,5-cyclohexadien-1-ones is governed by electronic rather than steric effects to give the intermediate C(1) rather than C(3) substituted bicyclo [3.1.0(1,5)]hex-3-en-2-ones. Regioselectivities of the acid-catalyzed dienone-phenol rearrangements of C(2) substituted 2,5-cyclohexadienones 11, 45a, and 45b appear to be dependent upon the relative stabilities of carbocations resulting from migration of the C(4) carbomethoxy group.

  functions as a selective oxidant for the transformation of arenes to phenols under mild conditions. Although the reaction proceeds through a radical mechanism, aromatic C–H bonds are selectively oxidized in preference to activated –H bonds. Notably, a wide array of functional groups are compatible with this reaction, and this method is therefore well suited for late-stage transformations of advanced

  碳氢 (C-H) 键氧化方法在合成有机化学中具有重要作用，可提供最终目标分子所需的功能或促进后续化学转化。已经描述了几种氧化脂肪族 C-H 键的方法，大大简化了复杂分子的合成。然而，在温和条件下选择性氧化芳族 C-H 键，尤其是在具有不同官能团的取代芳烃的情况下，仍然是一个挑战。芳烃的直接羟基化最初是通过使用强布朗斯台德或路易斯酸与超化学计量当量的氧化剂介导亲电芳香取代反应来实现的，这显着限制了反应范围。由于这些反应的产物比起始材料更具反应性，因此过度氧化通常是一个竞争过程。已经开发了过渡金属催化芳烃的 C-H 氧化，有或没有导向基团，改进了酸介导的过程；但是，需要贵金属。在这里，我们证明过氧化邻苯二甲酰作为选择性氧化剂在温和条件下将芳烃转化为酚类。尽管反应通过自由基机制进行，但芳香族 C-H 键优先于活化的 -H 键被选择性氧化。值得注意的是，大量的官能团与该反应相容，因此该方法非常适合

  Bifunctional compounds, which find utility as modulators of androgen receptor (AR), are described herein. In particular, the bifunctional compounds of the present disclosure contain on one end a moiety that binds to the cereblon E3 ubiquitin ligase and on the other end a moiety which binds AR, such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of target protein. The bifunctional compounds of the present disclosure exhibit a broad range of pharmacological activities associated with degradation/inhibition of target protein. Diseases or disorders that result from aberrant regulation of the target protein are treated or prevented with compounds and compositions of the present disclosure.
