Chiral quaternary phosphonium salts: a new class of organocatalysts
MetadataShow full item record
Phase-transfer catalysis has widely been used as a prime synthetic tool for both laboratory and industrial processes. During the last twenty years, asymmetric phase-transfer catalysis using chiral organocatalysts has attracted widespread interest. However, the scope of chiral phase-transfer catalysis has been limited mostly to the quaternary ammonium salts. As an emerging area, the recent developments in the application of quaternary phosphonium salts as chiral phase-transfer catalysts are discussed in this article.

Homochirality in biomineral suprastructures induced by assembly of single-enantiomer amino acids from a nonracemic mixtureJiang, W.; Athanasiadou, D.; Zhang, S.; Demichelis, Raffaella ; Koziara, Katarzyna; Raiteri, Paolo ; Nelea, V.; Mi, W.; Ma, J.A.; Gale, Julian ; McKee, M.D. (2019)© 2019, The Author(s). Since Pasteur first successfully separated right-handed and left-handed tartrate crystals in 1848, the understanding of how homochirality is achieved from enantiomeric mixtures has long been incomplete. ...
Vibrational circular dichroism of 3-(trifluoroacetyl)-camphor and its interaction with chiral aminesMerten, C.; Jalkanen, Karl; Weiss, V.; Hartwig, A. (2010)Vibrational circular dichroism (VCD) spectroscopy and density functional theory (DFT) calculations are used to investigate the keto-enol equilibrium of 3-(trifluoroacetyl)-camphor (TFC) and to study the interaction of TFC ...
