  Efficient Syntheses of the anti- and syn-Diol Epoxide Metabolites of the Carcinogenic Polycyclic Aromatic Hydrocarbon Benzo[g]chrysene

  摘要：

  Two new synthetic approaches to the active fjord region anti- and syn-diol epoxide metabolites (3a and 3b) of the potent carcinogenic hydrocarbon benzo[g]chrysene are described. The first of these methods entails initial synthesis of the key intermediate 12-hydroxybenzo[g]chrysene which is transformed in two steps to trans-11,12-dihydroxy-11,12-dihydrobenzo[g]chrysene, the synthetic precursor of 3a and 3b. The second method involves in the key step oxidative photocyclization of a 1,2 diarylethylene having methoxy groups at appropriate sites for subsequent conversion to the dihydrodiol function. These methods allow efficient preparative scale synthesis of the benzo[g]chrysene diol epoxides required as starting compounds for the synthesis of specifically alkylated benzo[g]chrysene-oligonucleotide adducts needed for site-directed mutagenesis and other studies to elucidate molecular mechanisms of carcinogenesis.

  日期：2017.9.1

  efficient synthetic approach to triphenylene-based polycyclic aromatic hydrocarbons (PAHs) from ring-fused benzocyclobutenols (RBCBs) through the cleavage of the C–C σ-bond. Two key transformations are involved: (a) palladium-catalyzed C–C bond (hetero)arylation of RBCBs; and (b) Lewis acid-promoted intramolecular annulation leading to complex polycyclic compounds. A variety of multiply substituted triphenylenes

  在本文中，我们公开了一种新的，有效的合成方法，该方法通过裂解C–Cσ键，从环稠合的苯并环丁烯醇（RBCB）中合成基于三苯撑的多环芳烃（PAH）。涉及两个关键的转变：（a）RBCBs的钯催化C–C键（杂）芳基化；（b）路易斯酸促进的分子内环化反应，产生复杂的多环化合物。以合成上有用的产率获得了多种多取代的联苯撑及其衍生物。
