Preferred gauche conformation in N-(2-aminoethyl)pyridinium ions
X-ray analysis of 1-[(2S, 3S)-2-N,N-dibenzylamino-3-methyl-1-pentyl]pyridinium p-toluenesulphonate and 1-[(2S)-2-N,N-dibenzylamino-1-propyl]pyridinium p-toluenesulphonate reveals that in both compounds the central N---C---C---N moiety is in the syn ...

A Synthetic Route to Quaternary Pyridinium Salt-Functionalized Silsesquioxanes
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 ...

Investigating the chemistry of pyridinium ylides [PDF]
This thesis describes investigation into catalytic formation of pyridinium ylides from diazo compounds and their subsequent reactivity. In particular, cycloaddition reactions with electrophilic alkenes are performed to generate tetrahydroindolizines that

Synthesis of Pyridinium Amphiphiles Used for Transfection and Some Characteristics of Amphiphile/DNA Complex Formation [PDF]
Pyridinium amphiphiles have found practical use for the delivery of DNA into cells. Starting from 4-methylpyridine, a general synthesis has been devised for the production of pyridinium amphiphiles which allows variation in both the hydrophobic part and ...
