Direct Determination of Absolute Molecular Stereochemistry in Gas Phase by Coulomb Explosion Imaging
Science, 2013 Absolute Images Molecules are held together by a balance of charge between negative electrons and positive nuclei. When multiple electrons are expelled by laser irradiation, the remaining, mutually repulsive nuclei fly apart in a Coulomb explosion ...

A Concise Total Synthesis of (--)-Maoecrystal Z [PDF]
, 2011 The first total synthesis of (--)-maoecrystal Z is described. The key steps of the synthesis include a diastereoselective Ti^(III)-mediated reductive epoxide coupling reaction and a diastereoselective Sm^(II)-mediated reductive cascade cyclization ...

Organotin(IV) Dithiocarbamate Complexes: Chemistry and Biological Activity
Molecules, 2018 Significant attention has been given to organotin(IV) dithiocabamate compounds in recent times. This is due to their ability to stabilize specific stereochemistry in their complexes, and their diverse application in agriculture, biology, catalysis and as

Focus on chirality of HIV-1 non-nucleoside reverse transcriptase inhibitors [PDF]
, 2016 Chiral HIV-1 non-nucleoside reverse transcriptase inhibitors (NNRTIs) are of great interest since one enantiomer is often more potent than the corresponding counterpart against the HIV-1 wild type (WT) and the HIV-1 drug resistant mutant strains.

The Chirality Of Life: From Phase Transitions To Astrobiology [PDF]
arXiv, 2008 The search for life elsewhere in the universe is a pivotal question in modern science. However, to address whether life is common in the universe we must first understand the likelihood of abiogenesis by studying the origin of life on Earth. A key missing piece is the origin of biomolecular homochirality: permeating almost every life-form on Earth is ...

Crystal structure of 9-methacryloylanthracene
Acta Crystallographica Section E: Crystallographic Communications, 2015 In the title compound, C18H14O, with systematic name 1-(anthracen-9-yl)-2-methylprop-2-en-1-one, the ketonic C atom lies 0.2030 (16) Å out of the anthryl-ring-system plane. The dihedral angle between the planes of the anthryl and methacryloyl moieties is
