Dynamic kinetic resolution–asymmetric transfer hydrogenation of 1-aryl-substituted cyclic ketones
摘要:
A range of 1-aryl-2-tetranols, and 1-phenyl-2-indanol, have been generated in high yield and enantiomeric excess from the corresponding racemic ketones, via a dynamic kinetic resolution-transfer hydrogenation process, using Ru(II)-TsDPEN in formic acid/triethylamine (5:2). This provides a potential entry to an asymmetric total synthesis of benzazepines such as Sch 39166. (C) 2002 Elsevier Science Ltd. All rights reserved.
