β,γ-Unsaturated amides are valuable substrates for downstream functionalization reactions but can be challenging to prepare. Herein, we introduce an approach featuring the regioselective addition of carbamoyl chlorides to unactivated alkenes, present its scope and limitations, and exemplify its synthetic utility.

To discover novel structural nematicides, 79 amide compounds containing 1,2,4/1,3,4-oxadiazole moiety were designed, synthesized, and evaluated for nematicidal efficacy against second-stage juveniles of (). Notably, some compounds exhibited superior nematicidal efficacy, for example, the LC values of compounds , , , , , , , and were 7.4, 31.

Seborrheic dermatitis (SD) is a chronic inflammatory skin disorder most commonly affecting areas rich in sebaceous glands, such as the scalp, face, axilla, and groin. Several factors can precipitate SD development, such as colonization of Malassezia, sebocyte activity, impaired immunity, and environmental influences. Topical antifungals, corticosteroids, and calcineurin inhibitors are the current mainstay treatment of SD.

Bacterial populations experience chemical gradients in nature. However, most experimental systems either ignore gradients or fail to capture gradients in mechanically relevant contexts. Here, we use microfluidic experiments and biophysical simulations to explore how host-relevant shear flow affects antimicrobial gradients across communities of the highly resistant pathogen .

Esters have been described as bioactive chemical compounds. However, the presence of an ester as a functional group is often associated with hydrolytic liability. Therefore, it is often unclear whether esters serve as pro-drugs and are rather converted into bioactive drugs in cells.
