Arylhydrazines: Convenient Homogeneous Reductants for Scalable Cross‐Coupling
Reductive cross‐couplings enable efficient C–C bond formation but are limited by the heterogeneity of Zn or costly reagents like TDAE. We report arylhydrazines as inexpensive, convenient reductants for Ni‐catalyzed sp2–sp3 coupling of aryl halides and secondary alkyl iodides. Mechanistic studies support hydrazine‐mediated NiII reduction for a NiI/NiIII

Systematic Chemoenzymatic Synthesis of O-Sulfated Sialyl Lewis x Antigens. [PDF]
O-Sulfated sialyl Lewis x antigens play important roles in nature. However, due to their structural complexity, they are not readily accessible by either chemical or enzymatic synthetic processes.

Biocatalytic preparation and absolute configuration of enantiomerically pure fungistatic anti-2-benzylindane derivatives. Study of the detoxification mechanism by Botrytis cinerea [PDF]
Enantiomerically pure 2-benzylindane derivatives were prepared using biocatalytic methods and their absolute configuration determined. (1R,2S)-2-Benzylindan-1-ol ((1R,2S)-2) and (S)-2-benzylindan-1-one ((S)-3) were produced by fermenting baker’s yeast.

Stereoselective cyclo-addition reactions of azomethine ylides catalysed by in situ generated Ag(I)/bisphosphine complexes [PDF]
Stereoselective cyclo-addition reactions of azomethine ylides promoted by in situ generated Ag(I)/bisphosphine complexes were studied. Under the optimised conditions, the pyrrolidine products were isolated in up to 84 % yield and with up to 71 % e.e. The
