STRIDER: Steric hindrance estimator [PDF]
, 2020 AbstractIn silicomodeling plays a vital role in thede novodesigning and docking of biomacromolecules as well as in exploring their conformational dynamics. Additionally, it has a major role in acquiring the structural insights from the parameters derived from the experimental techniques such as cryo-electron microscopy.

Observation of 1,3-Diketones Formation in the Reaction of Bulky Acyl Chlorides with Methyllithium
Molecules, 2012 The formation of 1,3-diketones was observed in the reactions of bulky acyl chlorides with methyllithium. The reaction products depend on the steric hindrance around the carbonyl group of the acyl chloride and the electronic effect of the group(s) linked ...

Scope and limitations of aliphatic Friedel-Crafts alkylations. Lewis acid catalyzed addition reactions of alkyl chlorides to carbon-carbon double bonds [PDF]
, 1983 Lewis acid catalyzed addition reactions of alkyl halides 1 with unsaturated hydrocarbons 2 have been studied. 1:l addition products 3 are formed if the addends 1 dissociate faster than the corresponding products 3; otherwise, polymerization of 2 takes ...

1,9-Bis(2-pyridyl)-1,2,8,9-tetrathia-5-oxanonane
Molbank, 2009 Disulfide crosslinking of proteins is typically performed by treating proteins bearing cysteine residues with small-molecule disulfide reagents. The process results in the formation of a mixed disulfide intermediate, which then reacts with the cysteine ...

Resummed thermodynamic perturbation theory for bond cooperativity in associating fluids with small bond angles: Effects of steric hindrance and ring formation [PDF]
, 2014 In this paper we develop a thermodynamic perturbation theory for two site associating fluids which exhibit bond cooperativity. We include both steric hindrance and ring formation such that the equation of state is bond angle dependent.
