  Synthetic Applications and Inversion Dynamics of Configurationally Stable 2-Lithio-2-arylpyrrolidines and -piperidines

  摘要：

  In diethyl ether, N-Boc-2-lithio-2-arylpiperidines have been found to be configurationally stable at -80 degrees C, whereas N-Boc-2-lithio-2-arylpyrrolidines are configurationally stable at -60 degrees C. Several tertiary benzylic carbanions derived from enantioenriched 2-aryl heterocycles have been successfully alkylated or acylated with little to no loss of enantiopurity. The scope of the reactions has been explored. The enantiomerization dynamics of N-Boc-2-lithio-2-phenylpyrrolidine and N-Boc-2-lithio-2-phenylpiperidine have been studied in the presence of different solvents and achiral ligands.

  通过光氧化还原催化将 α-氨基酸脱羧芳基化：生物质向药物药团的一步转化

  摘要：

  α-氨基酸的直接脱羧芳基化是通过可见光介导的光氧化还原催化实现的。这种方法提供了从丰富的生物质，特别是 α-氨基酸前体快速进入流行的苄胺结构的途径。在氨基酸和芳烃组分方面都观察到显着的底物范围。

  The direct decarboxylative arylation of α-amino acids has been achieved via visible light-mediated photoredox catalysis. This method offers rapid entry to prevalent benzylic amine architectures from an abundant biomass, specifically α-amino acid precursors. Significant substrate scope is observed with respect to both the amino acid and arene components.

  Nonactivated alcohols along with arene compounds are used in electrochemical dehydroxylative arylation for constructing C(sp3)–C(sp2) bonds. The PIII reagent undergoes single-electron anodic oxidation to form its radical cation, which reacts with the alcohol to produce an alkoxytriphenylphosphine radical. Through spontaneous β-scission of the phosphoranyl radical, the C–O bond is cleaved to form an

  非活化醇与芳烃化合物一起用于电化学脱羟基芳基化以构建 C(sp 3 )–C(sp 2 ) 键。P III试剂经过单电子阳极氧化形成其自由基阳离子，该阳离子与醇反应生成烷氧基三苯基膦自由基。通过磷酰基自由基的自发β-断裂，C-O键裂解形成烷基自由基物质，其与贫电子芳烃阴极还原产生的自由基阴离子偶联，得到脱羟基芳基化产物。

  electron-deficient (trifluoromethylsulfonyl)benzene derivatives, as a phenyl precursor, was critical to realizing the present transformation. Moreover, the DFT calculations indicated that the present transformation proceeds via a concerted homolytic aromatic substitution rather than via a stepwise one involving the formation of a cyclohexadienyl radical intermediate.

  使用光激发的 4-苯甲酰吡啶作为氢原子转移，在连接到醚和 N-Boc-胺的杂原子上的非酸性 C(sp 3 )–H 键上实现了一步苯基化（ HAT）催化剂。作为苯基前体的缺电子（三氟甲基磺酰基）苯衍生物的设计对于实现目前的转变至关重要。此外，DFT计算表明，本发明的转化是通过协同均裂芳族取代进行的，而不是通过涉及环己二烯基自由基中间体形成的逐步取代进行的。
