More than 60 derivatives of (2-nitrophenyl)methanol were synthesized and evaluated regarding their potency to inhibit PqsD. In vitro and in cellulo structure–activity relationships were derived.
A rhodium or palladium-catalyzedaddition of boronic acids to phthalaldehydonitrile, followed by an intramolecularlactonization of cyano to access 3-substituted phthalides, is described. This procedure tolerates a series of functional groups, such as methoxy, fluoro, chloro, and vinyl groups. It is a novel procedure for the synthesis of 3-arylphthalides.

compounds meet DMSO, a unique platform is set up to manipulate sulfonium chemistry. A case study of oxidation of alcohols to ketones is shown herein. Crucial trifluoromethoxysulfonium is initially generated, and reacts with alcohols to give new alkoxysulfonium species via ligand exchange. Subsequent base-promoted E2 elimination gives ketones with the release of Me2S.

Aldehydes and siloxanes form methyl esters in a single step through mild oxidative esterification in the presence of a palladium catalyst or, alternatively, afford secondary alcohols via TBAF-promoted arylation in the absence of a catalyst at increased temperatures under otherwise identical reaction conditions.
