On August 31, 2013, Claridge, Timothy D. W.; Davies, Stephen G.; Kruchinin, Dennis; Odell, Barbara; Roberts, Paul M.; Russell, Angela J.; Thomson, James E.; Toms, Steven M. published an article.Computed Properties of 168297-86-7 The title of the article was Solution phase structures of enantiopure and racemic lithium N-benzyl-N-(α-methylbenzyl)amide in THF: low temperature 6Li and 15N NMR spectroscopic studies. And the article contained the following:
The antipodes of lithium N-benzyl-N-(α-methylbenzyl)amide are highly efficient enantiopure ammonia equivalent for the asym. synthesis of β-amino acid derivatives via conjugate addition to α,β-unsaturated esters. 6Li and 15N NMR spectroscopic studies of doubly labeled 6lithium (S)-15N-benzyl-15N-(α-methylbenzyl)amide in THF at low temperature reveal the presence of lithium amide dimers as the only observable species. Either a monomeric or dimeric lithium amide reactive species can be accommodated within the transition state mnemonic for this class of conjugate addition reaction. This enantiopure lithium amide offers unique opportunities over achiral (e.g., lithium dibenzylamide) and C2-sym. (e.g., lithium bis-N,N-α-methylbenzylamide) counterparts for further mechanistic study owing to the ready distinction of the various dimers formed. The experimental process involved the reaction of (S)-4-Isopropyl-5,5-dimethyloxazolidin-2-one(cas: 168297-86-7).Computed Properties of 168297-86-7
