Methyl (S)-lactate as a chiral auxiliary in the asymmetric synthesis of Bao Gong Teng A.
Pham VC and Charlton JL.
The Journal of Organic Chemistry, 60(24), 8051-8055 (1995)
Katia Le Barbu-Debus et al.
Physical chemistry chemical physics : PCCP, 8(8), 1001-1006 (2006-02-17)
Two low energy conformers of the chiral (R)-1-aminoindan molecule are identified in supersonic jet and their ground and excited states vibrational spectroscopy has been investigated by laser-induced fluorescence (LIF) excitation and single vibronic level (SVL) emission spectroscopy. Ab initio calculations
Opposite signs of capacitive microsensor signals upon exposure to the enantiomers of methyl propionate compounds.
Petra Kurzawski et al.
Angewandte Chemie (International ed. in English), 47(5), 913-916 (2007-12-22)
K Le Barbu-Debus et al.
Physical chemistry chemical physics : PCCP, 11(35), 7589-7598 (2009-12-03)
Complexation between (1R,2S)-(+)-cis-1-amino-2-indanol (AI) and the two enantiomers of methyl lactate has been studied by means of laser-induced fluorescence, resonance-enhanced two-photon ionisation, and IR-UV double resonance spectroscopy, in the region of 3 microm. Two isomeric complexes have been spectroscopically characterised
Nicole Borho et al.
Organic & biomolecular chemistry, 1(23), 4351-4358 (2003-12-20)
Chiral recognition and subsequent selective self-organisation into hydrogen-bonded n-mers is observed in supersonic methyl lactate expansions. The nu(OH) and nu(C=O)-vibrations are investigated by ragout-jet FTIR-spectroscopy and lead to the assignment of homo- and heterochiral clusters of at least three different
