Convenient Synthesis of Stable Aldimine−Borane Complexes, Chiral δ-Amino Alcohols, and γ-Substituted GABA Analogues from Nitriles
摘要:
A one-pot synthesis of stable aldimine-trialkylborane adducts, the first synthesis of C- and N-deuterated imine-borane complexes, and their application for a highly enantioselective (84-99% ee) synthesis of delta-amino alcohols and gamma-substituted gamma-aminobutyric acids, including deuterated amino acids from nitriles, are described.
