, p. 153 - 163 (2000)
The two chiral lithium amides prepared from (R)-(2-N,N-dimethylamine-ethyl)-(1-phenyl-2-pyrrolidin-1-yl-ethyl)amine (1) and (R)-(2-methoxyethyl)-(1-phenyl-2-pyrrolidin-1-yl-ethyl)amine (2) and n-BuLi, were found to form symmetrically solvated dimers in di
Asymmetric synthesis of β-dialkylamino alcohols by transfer hydrogenation of α-dialkylamino ketones

experimental part, p. 1138 - 1143 (2009/09/27)
Transfer hydrogenation of representative aryl and heteroaryl dialkylaminomethyl ketones with formic acid-triethylamine, catalyzed by RuCl[(R,R)-TsDPEN](η-p-cymene), produces the corresponding β-dialkylamino alcohols, 97-99% ee, in 50-73% yields. Asymmetric synthesis of (R)-macromerine, 98% ee, the cactus Coryphantha macromeris alkaloid, is also described.
