Synthesis of 2-phenyl-4,5,6,7-tetrahydro-1H-indoles with a chiral substituent at the nitrogen atom
摘要:
An efficient method has been developed for the enantioselective synthesis of 2-phenyl-4,5,6,7-tetra-hydro-1H-indoles containing chiral substituents at the nitrogen atom. It is based on opening of the epoxide fragment of 1-phenylethynyl-7-oxabicyclo[4.1.0]heptane with chiral amines and/or amino acid esters followed by intramolecular, metal catalyzed cyclization.
