Tang, Wan-Ying,Chen, Ling,Zheng, Ming,Zhan, Le-Wu,Hou, Jing,Li, Bin-Dong
supporting information, p. 3939 - 3943 (2021/05/26)
A photoinduced oxidative alkoxycarbonylation of alkenes initiated by intermolecular addition of alkoxycarbonyl radicals has been demonstrated. Employing alkyl formates as alkoxycarbonyl radical sources, a range of α,β-unsaturated esters were obtained with good regioselectivity and E selectivity under ambient conditions.

A new series of ester analogues of artemisinin 8a–f, incorporating diphenylmethyl as pharmacologically privileged substructure, and 8g–j have been prepared and evaluated for their antimalarial activity against multidrug-resistant (MDR) Plasmodium yoelii nigeriensis in Swiss mice via oral route. These diphenylmethyl-based ester analogues 8a–f were found to be 2–4 folds more active than the antimalarial drugs β-arteether 4 and artesunic acid 5. Ester 8a, the most active compound of the series, provided complete protection to the infected mice at 24?mg/kg?×?4?days as well as 12?mg/kg?×?4?days, respectively. In this model β-arteether provided 100% and 20% protection at 48?mg/kg?×?4?days and 24?mg/kg?×?4?days, respectively.

A variety of functionalized coumarins were synthesized from substituted phenylacrylic acids via PIDA/I2-mediated and irradiation-promoted oxidative carbon-oxygen bond formation. Our studies show that the oxygen in the pendant carboxylic acid group cyclizes favorably to the aryl ring that is cis to it. The main advantages of this method include good functional group tolerance and the transition-metal-free characteristic. The Royal Society of Chemistry 2013.
Palladium-catalyzed double arylations of terminal olefins in acetic acid
Xu, Daichao,Lu, Chunxin,Chen, Wanzhi
experimental part, p. 1466 - 1474 (2012/03/08)
A palladium-catalyzed Heck diarylation of terminal olefins under ligand-free conditions in acetic acid is described. This procedure allows double arylation of terminal olefins affording trisubstituted olefins in good to excellent yields. The methodology is applicable to the coupling of both electron-deficient and electron-rich aryl iodides leading to symmetrical and unsymmetrical β,β-diarylated alkenes.
Palladium-catalyzed intramolecular amidation of C(sp2)-H bonds: Synthesis of 4-aryl-2-quinolinones
Inamoto, Kiyofumi,Saito, Tadataka,Hiroya, Kou,Doi, Takayuki
supporting information; experimental part, p. 3900 - 3903 (2010/07/05)
Figure presented A catalytic synthetic approach for the synthesis of 2-quinolinone compounds through a Pd-catalyzed C(sp2)-H functionalization/intramolecular amidation sequence is described. The cyclization process efficiently proceeds in the p

Sauerberg, Per,Olsen, Grith S.,Jeppesen, Lone,Mogensen, John P.,Pettersson, Ingrid,Jeppesen, Claus B.,Daugaard, Jens R.,Galsgaard, Elisabeth D.,Ynddal, Lars,Fleckner, Jan,Panajotova, Vladimira,Polivka, Zdenek,Pihera, Pavel,Havranek, Miroslav,Wulff, Erik M.
, p. 1495 - 1503 (2008/02/03)
The aim was to identify a novel selective PPARδ agonist with full efficacy on free fatty acid (FFA) oxidation in vitro and plasma lipid correction in vivo. Using the triple PPARα,γ,δ agonist 1 as the structural starting point, we wanted to investigate the
