Racemic compound against racemic conglomerate formation: The crystal properties of allylbenzylmethylphenylphosphonium iodide as compared with the nitrogen analogue

Chirality, 2008
AbstractAlthough racemic allylbenzylmethylphenylammonium iodide 1b displays spontaneous resolution crystallizing in a homochiral mode as a conglomerate, its phosphonium analogue rac‐2b crystallizes in a heterochiral lattice forming racemic compound in the solid state.

Racemization and the origin of optically active organic compounds in living organisms

Biosystems, 1987
The organic compounds synthesized in prebiotic experiments are racemic mixtures. A number of proposals have been offered to explain how asymmetric organic compounds formed on the Earth before life arose, with the influence of chiral weak nuclear interactions being the most frequent proposal. This and other proposed asymmetric syntheses give only slight

QSAR analysis of chiral compounds including racemates.

Progress in clinical and biological research, 1989
From equations describing dose/response curves of drug combinations the nonlinear dependence of the ECx value (concentration for X% effect) of a racemate on the ECx values of the pure enantiomers was derived. This equation was used in QSAR analyses of series of substances containing pure compounds (i.e.
