Lipase catalysed kinetic resolution of racemic 1,2-diols containing a chiral quaternary center [PDF]
, 2018 Optically active 1,2-diols are valuable buildings blocks in organic synthesis. In the present paper, a set of racemic 1,2-diols with an ester functional group are prepared, starting from -ketoesters in a three-step procedure with moderate yields.

Racemic DNA Crystallography [PDF]
Angewandte Chemie, 2014 AbstractRacemates increase the chances of crystallization by allowing molecular contacts to be formed in a greater number of ways. With the advent of protein synthesis, the production of protein racemates and racemic‐protein crystallography are now possible.

Lattice and thermodynamic characteristics of N-stearoyl-allo-threonine monolayers
, 2020 The effect of the second chiral center of diastereomeric N-alkanoyl-allo-threonine on the main monolayer characteristics has been investigated. The characteristic features of the enantiomeric and racemic forms of N-stearoyl-allo-threonine monolayers are ...

Uni-directional polymerization leading to homochirality in the RNA world [PDF]
, 2005 The differences between uni-directional and bi-directional polymerization are considered. The uni-directional case is discussed in the framework of the RNA world. Similar to earlier models of this type, where polymerization was assumed to proceed in a bi-

Phase chirality and stereo-selective swelling of cholesteric elastomers [PDF]
, 2003 Cholesteric elastomers possess a macroscopic ``phase chirality'' as the director n rotates in a helical fashion along an optical axis $z$ and can be described by a chiral order parameter.
