Use of N,N'-dimethylpropyleneurea (DMPU) as solvent in the efficient preparation of enantiomerically pure secondary amines
Juaristi,Murer,Seebach
, p. 1243 - 1246 (1993)
The monoalkylation of (R)- and (S)-1-phenylethylamine proceeds readily with DMPU as the solvent. An efficient procedure was then developed for the high-yield preparation of the chiral secondary amines N-benzyl-, N-isopropyl-, N-(2-biphenylyl)methyl-, N-(diphenyl)methyl-, and N-(2,2-dimethyl)propyl-1-phenylethylamine, in enantiomerically pure form.
Amidures de lithium chiraux; β-elimination de trityllithium a partir d'un amidure de lithium
Plaquevent, Jean-Christophe,Ravard, Alain
, p. C51 - C53 (2007/10/02)
The synthesis of a chiral secondary amine bearing a N-CH2-trityl moiety is described.The formation of the corresponding lithium amide results in the β-elimination of trityllithium, leading to an intermediate methyleneamiine, which can react with nucleophiles.
