Reaction of Pyridinium Salts with Active Methylene Compounds
YAKUGAKU ZASSHI, 2006 The carbon-carbon bond-forming reactions of 1-methyl-2-methylthiophenylpyridinium iodides with active methylene compounds (such as dimethyl malonate, malononitrile) using NaH as a base gave the 2-substituted methylene-1,2-dihydropyridine derivatives.

Multivalent RNA‐Cleaving Agents on a Cubic Octameric Silsesquioxane Core
Chemistry – A European Journal, EarlyView.RNA‐cleaving agents on a cubic octameric silsesquioxane core were synthesized and characterized. Several catalytic systems of these structures were screened using hexaribonucleotide models. The best systems were then further used to study their catalytic efficiency in cleaving a HER2 mRNA model sequence. The induced cleavage sites were also determined.

A Synthetic Route to Quaternary Pyridinium Salt-Functionalized Silsesquioxanes
International Journal of Polymer Science, 2012 A synthetic route to potentially biocidal silsesquioxanes functionalized by quaternary pyridinium functionalities has been developed. N-Alkylation reactions of the precursor compounds 4-(2-(trimethoxysilyl)ethyl)-pyridine (5) and 4-(2-trichloro ...

Chemistry – A European Journal, EarlyView.Nonafluoromesitylsulfonyl (Nms)‐substituted oxycarbamates are introduced as redox‐lowered radical precursors for green‐light photoredox synthesis. Selective N─O bond cleavage generates amidyl radicals that directly aminate indolizines in DMF, whereas DMSO promotes 1,2‐hydrogen atom transfer (HAT) to α‐amino carbon‐centered radicals and C─C bond ...
