The present disclosure provides pharmaceutical compositions comprising 2-arylsulfonamido-N-arylacetamide derivatized Stat3 inhibitors and certain pharmaceutically acceptable salts thereof, and methods of their use.
Catalyticα‐alkylation of esters with primary alcohols is a desirable process because it uses low‐toxicity agents and generates water as the by‐product. Reported herein is a NCP pincer/Ir catalyst which is highlyefficient for α‐alkylation of a broad scope of unactivated esters under mild reaction conditions. For the first time, alcohols alkylate unactivated α‐substituted acyclic esters, lactones,

In one embodiment, the present invention is directed to a method for synthesizing compounds of the formula
where C
m
is a fullerene having m carbon atoms, the method comprising the steps of forming a linear malonate compound of the formula
where each Z is the same or different and is a straight-chain or branched-chain aliphatic radical having from 1-30 carbon atoms which may be unsubstituted or monosubstituted or polysubstituted by identical or different substitutents, in which radicals up to every third —CH
2
— unit can be replaced by O or NR″, n is an integer from 2 to 10, and the unfilled valences of the first and nth malonate groups are filled with bonds to hydrogen, a hydrocarbon group or substituted hydrocarbon group having 1-20 carbon atoms, or a chain containing unsubstituted or substituted aryl or other cyclic groups; or (ii) a branched malonate compound of the formula
where Z′ is an aliphatic radical having from 1-30 carbon atoms which may be unsubstituted or monosubstituted or polysubstituted by identical or different substitutents, in which radicals up to every third —CH
2
— unit can be replaced by O or NR″; and n is an integer from 2 to 10;
reacting said malonate compound with C
m
to form an adduct of the formula
each Z is bonded to both one carboxylate group of a first malonate moiety and one carboxylate group of a second malonate moiety and the unfilled valences of the first and nth malonate groups are filled with bonds to hydrogen, a hydrocarbon group or substituted hydrocarbon group having 1-20 carbon atoms, or a chain containing unsubstituted or substituted aryl or other cyclic groups; and hydrolyzing said adduct to form the compound.

while iron(III)-based couplings appear to proceed through a non-templated heterodimerization. This work presents the most in-depth findings on the mechanism of oxidativeenolate coupling to date. The scope of oxidativeenolateheterocoupling is extensive (40 examples) and has been shown to be efficient even on a large scale (gram-scale or greater). Finally, the method has been applied to the total synthesis
这篇完整的报告介绍了两种不同羰基物质的氧化分子间偶联的背景、发现和广泛的见解。该过程的优化最终形成了使用可溶性铜 (II) 或铁 (III) 盐作为氧化剂将酰胺、酰亚胺、酮和羟吲哚结合的可靠且可扩展的方案。广泛的机理研究表明,在铜 (II) 的情况下是金属螯合的单电子转移过程,而基于铁 (III) 的偶联似乎是通过非模板化的异二聚化进行的。这项工作提供了迄今为止对氧化烯醇偶联机制最深入的发现。氧化烯醇杂偶联的范围很广(40 个例子),并且已被证明即使在大规模(克级或更大)上也是有效的。最后,

negative charges, respectively, were examined with respect to electrostatic complexation with Cytochrome c (Cytc). To facilitate comprehensive photophysical investigations, the zinc analogue of Cytc (ZnCytc) was prepared according to a novel, modified procedure. The association of ZnCytc and DF, and consequential photoinducedelectrontransfer within ZnCytc-DF from the photoexcited protein to the fullerene
