A series of chalcones a1–20 bearing a 4-OMe groups on the A-ring were initially synthesized and their anticancer activities towards HepG2 cells evaluated. Subsequently, a series of chalcones b1–42 bearing methoxy groups at the 2' and 6'-positions of the B-ring were synthesized and their anticancer activities towards five human cancer cell lines (HepG2, HeLa, MCF-7, A549 and SW1990) and two non-tumoral human cell lines evaluated. The results showed that six compounds (b6, b8, b11, b16, b18, b22, b23 and b29) displayed promising activities, with compounds b22 and b29 in particular showing higher levels of activity than etoposide against all five cancer cell lines. Compound b29 showed a promising SI value compared with both HMLE and L02 (2.1–6.5 fold in HMLE and > 33 > 103.1 fold in L02, respectively).

Chalcones are bioactive compounds obtained from either natural sources or synthetic procedures and widely used due to their several biological properties. The most common experimental methodology in obtaining these compounds is Claisen–Schmidt reaction, which is a particular type of aldolic condensation. In this work, we have synthesized 23 chalcones and by density functional theory (DFT) calculation
A visible-light-driven and room temperature photo-Wolff-Kischner reaction of sulfur ylides and N-tosylhydrazones has been developed for the first time to provide modular access to alkene synthesis. The high functional group tolerance and broad substrate scope were demonstrated by more than 60 examples. Both E- and Z-olefinic stereochemistry in the products could be controlled with excellent stereoselectivity

types of cancer found in infants, and traditional chemotherapy has limited efficacy against this pathology. Thus, the development of new compounds with higher activity and selectivity than traditional drugs is a current challenge in medicinal chemistry research. In this study, we report the synthesis of 21 chalcones with antiproliferative activity and selectivity against the neuroblastoma cell line SH-SY5Y
Palladium-catalysed Suzuki–Miyaura couplings of α,β-unsaturated acid derivatives are challenging due to the susceptibility of their CC bonds adjacent to carbonyl groups. In this work, we describe a highly selective C–O activation approach to this transformation using superactive triazine esters and organoborons as coupling partners. 42 α,β-unsaturated ketones with diverse functional groups have been
钯催化的 α,β-不饱和酸衍生物的 Suzuki-Miyaura 偶联具有挑战性,因为它们的 C C 键与羰基相邻。在这项工作中,我们描述了一种使用超活性三嗪酯和有机硼作为偶联伙伴来实现这种转化的高选择性 C-O 活化方法。用该方法制备了 42 种具有不同官能团的 α,β-不饱和酮。机理研究表明,三嗪激活 C-O 键和稳定催化剂与底物之间的非共价相互作用的双重功能对于反应的成功至关重要。该方法的效率、功能组兼容性和独特的机制使其成为经典方法的有价值的替代品。
