New Aniline-Containing Amino Alcohols from trans-(R,R)-2-(2-Nitrophenyl)-3-phenyloxirane as Useful Intermediates for the Synthesis of Chiral Ligands, Bases, and Benzoxazine Nucleus
摘要:
New enantiopure aniline-containing amino alcohols are directly derived from trans-(R,R)-2-(2-nitrophenyl)-3-phenyloxirane, by alternative regioselective double reductions. Subsequent selective alkylation procedures and derivatizations provide a rapid and high-yielding access to different chiral ligands, bases, and benzoxazines, without loss of optical purity.
