  4-Dihydroxyborylphenyl Analogues of 1-Aminocyclobutanecarboxylic Acids:  Potential Boron Neutron Capture Therapy Agents

  摘要：

  A series of 4-dihydroxyborylphenyl analogues of an unnatural alpha-amino acid, 1-aminocyclobutanecarboxylic acid (ACBC), was synthesized. Varying numbers of methylene units were introduced between the 4-boronophenyl and ACBC moieties in order to introduce different degrees of lipophilicity into the molecules. The key step in the syntheses was the preparation of the precursor p-boronophenyl-substituted cyclobutanones which were subsequently converted to the desired amino acids via the Bucherer-Strecker reaction.

  A transition-metal-free direct trifluoromethylthiolation of the ipso-carbon of lithium aryl boronates with trifluoromethanesulfenate under mild conditions was described. In addition, late-stage site-selective C–H borylation/trifluoromethylation and C–Cl borylation/trifluoromethylthiolation of biologically active molecules was developed. Initial mechanistic study suggested that the Li+ cation plays

  的过渡金属-自由直接trifluoromethylthiolation本位被描述用温和的条件下trifluoromethanesulfenate锂芳基硼酸酯的碳上。此外，还开发了生物活性分子的后期现场选择性C–H硼化/三氟甲基化和C–C1硼化/三氟甲基硫醇化。最初的机理研究表明，Li +阳离子通过与芳基硼酸酯络合物的氧原子和试剂的氧配位发挥至关重要的作用，从而使芳基直接攻击三氟甲基硫醇化试剂的三氟甲硫基。
