  摘要：

  硼烷-硫化甲基（BMS）还原各种N-取代的琥珀酰胺和戊二酰胺酯，可以高产率地得到相应的N-取代吡咯烷和哌啶。这一转化过程中，由于胺氮周围的空间阻碍限制，以及通过不完全反应和/或合成后续的BMS还原检测到的假定中间体，表明环化作用和酰胺还原成功地与酯还原竞争，从而得到了N-取代的环化胺。

  4,4′-Di-tert-butylbiphenyl-catalysed reductive opening of azetidines with lithium: A direct preparation of 3,N-dilithioalkylamines

  摘要：

  The reaction of N-phenylazetidine 1a with an excess of lithium powder and a catalytic amount of 4,4'-ditert-butylbiphenyl (5 mol %) in THF at -15 degrees C leads to the corresponding dianion 2a, which by treatment with different electrophiles (H2O, D2O, Bu(CHO, PhCHO, (CH2)(5)CO, PhCH=NPh, CO2) yields, after hydrolysis with mater, the expected functionalysed amines 3aa-ah. The same method applied to N-isopropyl-2-phenylazetidine Ic affords compounds 3ca-ce (electrophiles: H2O, D2O, PhCHO, Me(2)CO, CH2=CHCH2Br) resulting from the more stable benzylic intermediate 2c. Finally, the regiochemistry in the reductive opening of 2-methyl-N-phenylazetidine Id followed by deuterolysis was studied: a mixture of both regioisomers 3da+3da' was obtained, the ratio being the oposite as expected according to the stability of both intermediates 2d and 2d'.

  A tin‐ and halide‐free, visible‐light photoredox‐catalyzed Giese reaction was developed. Primary and secondary α‐amino radicals were generated readily from amino acids in the presence of catalytic amounts of an iridium photocatalyst. The reactivity of the α‐amino radicals has been evaluated for the functionalization of a variety of activated olefins.

  support a mechanism which is initiated by a single electron transfer from N-aryl glycinate to the photochemically excited rhodium-bound α-chloro imidazol-2-yl-ketone, followed by chloride fragmentation of the α-chloroketone, decarboxylation of the glycinate, and a subsequent highly stereocontrolled radical-radical coupling. This work showcases the ability of the chiral rhodium catalyst to serve a dual function

  A method for the synthesis of γ‐amino sulfones through visible light‐induced oxidative decarboxylation and radical reductive addition is described. Various readily available N‐protected natural amino acids react with aromatic/aliphatic vinyl sulfones to directly produce γ‐amino sulfone derivatives. This reaction is also applicable to α‐N(O)‐acids and other aliphatic carboxylic acids, resulting in the
