Racemic (RSC,SRS)-(2-{[1-allyloxycarbonyl-3-(methylsulfanyl)propyl]iminomethyl}phenyl-κ3S,N,C1)chloridoplatinum(II)

Acta Crystallographica Section E, 2009
The title compound, [Pt(C15H18NO2S)Cl], was obtained by the cyclometallation reaction of cis-bis(benzonitrile)dichloridoplatinum(II) with N-benzylidene-l-methionine allyl ester in refluxing toluene. The PtII atom has a square-planar geometry and is tetra-

Redox-enabled direct stereoconvergent heteroarylation of simple alcohols

Nature Communications, 2021
Synthesizing complex structures of high enantiomeric excess from racemic feedstock is an enduring challenge. Here, the authors couple racemic secondary alcohols with pyrroles to form enantioenriched 2-substituted heteroarenes, via a borrowing hydrogen ...

Ethyl 4-[(2-hydroxyethyl)amino]-2-(4-methoxyphenyl)-1-methyl-5-oxo-2,5-dihydro-1H-pyrrole-3-carboxylate

IUCrData
In the title compound, C17H22N2O5 the pyrrolidine ring is almost planar and subtends a dihedral angle of 85.77 (7)° with the pendant phenyl ring. An intramolecular N—H...O hydrogen bond generates an S(6) loop. In the crystal, the compound forms inversion

Spontaneous Elliptical Polarization of Racemic Multilayer Polymers and Oligomers [PDF]

It is well-known that racemic molecules are elliptically inactive. Herein, we found novel racemic multilayer polymers and oligomers that are generated from catalytic polymerization can asymmetrically rotate the plane-polarized circular light to the right-

Monomer/Oligomer Quasi-Racemic Protein Crystallography [PDF]

, 2016
Racemic or quasi-racemic crystallography recently emerges as a useful technology for solution of the crystal structures of biomacromolecules. It remains unclear to what extent the biomacromolecules of opposite handedness can differ from each other in ...
