Target analysis of α-alkylidene-γ-butyrolactones in uropathogenic E. coli
Kunzmann, Martin H.,Sieber, Stephan A.

α-Alkylidene-γ-butyrolactones are quite common in nature and exhibit a broad spectrum of biological activities. We therefore synthesized a small library of xanthatine inspired α-alkylidene-γ-butyrolactones to screen non-pathogenic and uropathogenic E. col
Substrate-Selectivity in Catalytic Photooxygenation Processes Using a Quinine-BODIPY System
Coeffard, Vincent,Fischer, Jér?me,Nun, Pierrick,Serier-Brault, Hélène
, p. 463 - 468 (2020)
Substrate selectivity by means of synthetic catalysts remains a challenging topic in chemistry. Here, a catalytic system combining an iodo-BODIPY photosensitizer and quinine was evaluated in the competitive photooxygenation of non-hydrogen and hydrogen-bond-donor substrates. The ability of quinine to activate hydrogen-bond-donor substrates towards photooxygenation was reported and the results were benchmarked with photooxygenation experiments in the absence of quinine.
Reactions of p-Quinols with Aldehydes and Imines: Stereoselective Access to Polyheterobicyclic and Tricyclic Systems
García-García, Carolina,Redondo, María C.,Ribagorda, María,Carre?o, M. Carmen
, p. 7377 - 7388 (2014)
Dihydrobenzo[1,3]dioxolanones, tetrahydrobenzo[d]oxazolones and heterotricyclic derivatives have been stereoselectively synthesized from p-quinols upon reaction with aldehydes or benzaldimines under basic catalysis. Reactions occurred in an experimentally
