modular ligand library, high-throughput experimentation, and rational ligand evolution have led to a novel copper catalyst for the synthesis of phenols with a traceless hydroxide surrogate. The mild reaction conditions reported here enable the late-stage synthesis of numerous complex, druglike phenols.

Anthranilic diamides is a class of insecticides target at ryanodinereceptors (RyRs). To discover potent insecticides targeting at RyRs, a series of novel anthranilic diamides with a diacylhydrazine bridge were designed and synthesized. Their insecticidal activities were evaluated and a preliminary structure‐activity relationship (SAR) was summarized. In particular, compound 5g exhibited good lethality

A series of novel 2,3-dihydro-1,3,4-oxadiazoles containing N-pyridylpyrazole carboxamides moieties were obtained by applying a new synthetic route. Their insecticidal tests against oriental armyworm (Mythimna separata) and diamondback moth (Plutella xylostella) indicated that most of the compounds showed moderate to excellent activities at the testing concentrations. In particular, compound 6a showed 40% larvicidal activities against oriental armyworm at 1 mg/L, while 7a against diamondback was 100% at 0.01 mg/L. Calcium imaging results demonstrated that 6a, 6d and 7a stimulated a transient elevation in [Ca2+](i) in the absence of external calcium after the central neurons dye loading with fluo-3 AM, implying that these novel compounds were potential activators of the ligand-gated calcium channel on the endoplasmic reticulum.
