A simple proline-based organocatalyst for the enantioselective reduction of imines using trichlorosilane as a reductant
摘要:
A simple and inexpensive proline-based organocatalyst was developed for the reduction of imines using trichlorosilane as a reductant. The reduction of N-aryl imines in the presence of 10 mol % of N-pivaloyl-L-proline anilide was carried out to give the corresponding amines in excellent yields (up to 99%) with high enantioselectivities (up to 93% ee).

A new amide bond activation paradigm through amino acid insertion enabled by two tandem intramolecular rearrangements is reported. This strategy only requires stable and readily available amide and amino acid as the starting materials, which does not need any pre-functionalization as well as the isolation of reaction intermediates.
