Trifluoromethyl ketones were found to be inhibitors of histone deacetylases (HDACs). Optimization of this series led to the identification of submicromolar inhibitors such as 20 that demonstrated antiproliferative effects against the HT1080 and MDA 435 cell lines.

Photocatalytic Three-Component Reductive Coupling Synthesis of -Difluorohomoallyl Secondary Amines.

J Org Chem

Key Laboratory of the Ministry of Education for Advanced Catalysis Materials, College of Chemistry and Materials Sciences, Zhejiang Normal University, 688 Yingbin Road, Jinhua 321004, P. R. China.

-Difluorohomoallyl amines, an important class of -difluoroalkenes, are prevalent moieties in many bioactive compounds. However, limited methods are suitable for the synthesis of this type of compound containing secondary amines. Here, we display a photocatalytic multicomponent protocol for the synthesis of -difluoroalkenes containing secondary amines, which makes use of readily available materials: arylamines, alkyl aldehydes, and α-trifluoromethyl alkenes.

Lipid metabolic remodeling delays senescence of T cells to potentiate their immunity against solid tumors.

J Immunother Cancer

Background: Tumor cells can drive the senescence of effector T cells by unbalancing their lipid metabolism, thereby limiting adoptive T cell therapy and contributing to tumor immune evasion. Our objective is to provide a feasible strategy for enhancing T cell treatment efficacy against solid tumors.

Methods: In this study, liposomal arachidonyl trifluoromethyl ketone (ATK) was anchored onto the adoptive T cell surface via bioorthogonal reactions, aiming to specifically inhibit the group IVA cytosolic phospholipase Aα (cPLAα), a key enzyme facilitating phospholipid metabolism and senescent state of T cells.

A novel and efficient 1,2-oxidative trifluoromethylation of olefins employing Ag(OCCFSOF) as a trifluoromethyl source is described with O as the oxidant, which provides access to a variety of valuable α-trifluoromethyl-substituted ketones. The broad substrate scope, feasibility of large-scale operation, and derivatization reactions of α-trifluoromethyl ketones demonstrate the promising utility of this protocol.

Herein, we report the rhodium-catalyzed -alkenyl transfer from tertiary allylic alcohols to aryl trifluoromethyl ketones, which provided an efficient way of preparation of trifluoromethyl-containing -allylic alcohols via β--alkenyl elimination. The key -alkenyl-rhodium species were generated with a high degree of stereochemical retention. This reaction featured a broad substrate scope and good functional tolerance and would offer a fascinating approach for the synthesis of -alkenes.

We report an efficient synthetic route to the metal-free hydroboration and cyanosilylation of a wide range of alkynyl trifluoromethyl ketones using pinacolborane (4,4,5,5-tetramethyl-1,3,2-dioxaborolane) and trimethylsilyl cyanide under mild reaction conditions at ambient temperature. These highly effective hydroboration and cyanosilylation reactions lead to the corresponding alkynyl trifluoromethyl propargyl alcohols after hydrolysis. In addition, trifluoromethyl (CF) group-based pharmaceutically active enflicoxib analogs were synthesized from propargyl alcohol.
