Lu, Ting,Gu, Liuqun,Kang, Qiang,Zhang, Yugen
, p. 6602 - 6605,4 (2012)
A series of novel diphenyl ethylenediamine (DPEN) derived C2 symmetric dihydroimidazolium cyclophanes were designed and synthesized as organo NHC precatalysts. The resultant organo NHC-catalyzed reactions with superior enantioselectivity than t

Known PTP1B inhibitors with bis-anionic moieties exhibit potent inhibitory activity, good selectivity, however, they are incapable of penetrating cellular membranes. Based upon our finding of a new pharmacophoric group in inhibition of PTP1B and the struc
Multicomponent synthesis of new bis(pyranopyrazoles) and their antimicrobial–antioxidant evaluations
Yusuf, Mohamad,Thakur, Saloni
, p. 119 - 128 (2019/05/15)
One-pot, three-component reactions were utilized to obtain a series of new symmetrical bis(pyranopyrazoles) built around six rigid linkers in good yields and in the short durations under normal conditions. The structures of the prepared compounds were confirmed using their IR, 1H-NMR, 13C-NMR and ESI-MS spectral parameters. The bis(pyranopyrazoles) 3b and 3f exhibited significant antimicrobial action against Klebsiella pneumoniae, Fusarium oxysporum and Penicillium glabrum at a minimum inhibitory concentration (MIC) value of 3.12 μg mL-1, which is equivalent to the MIC of the standard drug. trans-Butene-linked bis(pyranopyrazole) 3f was also associated with a good radical scavenging activity similar to that of ascorbic acid (a standard antioxidant).

Four-step route to novel bisflavylium dications - First synthesis of phloroglucinol-type derivatives
Kueny-Stotz, Marie,Brouillard, Raymond,Chassaing, Stefan
supporting information, p. 2053 - 2058,6 (2020/07/31)
Various bisflavylium dications have been prepared in an efficient four-step manner utilizing the acid-mediated condensation between bis(arylethynylketones) and activated phenols as the key step. Of special note is that phloroglucinol-type bisflavylium sal
Synthesis and characterization of new organic phosphonates monomers as flame retardant additives for polymers
Finocchiaro, Paolo,Consiglio, Giuseppe A.,Imbrogiano, Andrea,Failla, Salvatore
, p. 1689 - 1701 (2008/02/11)
Commercially available polyphenols react with diethylphosphite to give polyphosphonates, which are easily transformed by LDA in good yields to polyorthohydroxy aryl phosphonates. Moreover, some bis-benzyl aminobenzyl phosphonates have been prepared in good yields. These new monomers are of great relevance for the synthesis of thermal resistant polycondensates containing phosphonate moieties.
Tether-directed selective synthesis of fulleropyrrolidine bisadducts
Zhou, Zhiguo,Schuster, David I.,Wilson, Stephen R.
