Synthesis and Photochemistry of Tertiary Amine Photobase Generators

open access: yes, 2002
A family of tertiary amine photobase generators have been prepared and studied. The compounds investigated were quaternary ammonium salts of benzhydrylamine (aminodiphenylmethane) and 9-aminofluorene. The compounds were prepared by the following methods:

Direct Asymmetric α-Allylation of Aldehydes with Simple Allylic Alcohols Enabled by the Concerted Action of Three Different Catalysts

open access: yes, 2011
Triple catalysis: The title reaction between α‐branched aldehydes and allylic alcohols, which generates all‐carbon quaternary stereogenic centers, constitutes the first asymmetric Tsuji–Trost‐type α‐allylation of carbonyl compounds with allylic alcohol ...

A Mild and General Method for the Synthesis of 5-Substituted and 5,5-Disubstituted Fulleroprolines

open access: yes, 2016
The reductive ring-opening of fullerenyldihydropyrrole yields ethyl N-benzhydryl fullerenyl[60]glycinate, which is deprotected to give ethyl fullerenylglycinate.

LuxR dependent quorum sensing inhibition by N,N′-disubstituted imidazolium salts

open access: yes, 2011
International audienceThirty N,N'-disubstituted imidazolium salts have been synthesized and evaluated as LuxR antagonists. Substitution on one of the imidazolium nitrogen atoms includes benzhydryl, fluorenyl or cyclopentyl substituent, and alkyl chains ...
