A practical, solvent free, one-pot synthesis of C 2 -symmetrical secondary amines
摘要:
A novel one-pot reductive amination of ketones using the combination Ti((OPr)-Pr-i)(4)/H-2/Pd-C is reported. This practical procedure does not require any solvent, and affords C-2-symmetrical secondary amines in high yields and excellent diastereoselectivities. (C) 2003 Elsevier Ltd. All rights reserved.
