A highly novel and direct synthesis of benzoxazinones was developed via Cp*Co(III)-catalyzed C–H activation and [3 + 3] annulation between sulfoxonium ylides and dioxazolones. The reaction is conducted under base-free conditions and tolerates various functional groups. Starting from diverse readily available sulfoxonium ylides and dioxazolones, a variety of benzoxazinones could be synthesized in one step in 32%-75% yields.

A highly efficient and practical heterogeneous palladium-catalyzed carbonylative coupling of 2-iodoanilines with aryl iodides has been developed. The reaction occurs smoothly in toluene at 110 °C with N, N -diisopropylethylamine as base under carbon monoxide (5 bar) and offers a general and powerful tool for the construction of various valuable 2-arylbenzoxazinones with excellent atom-economy, high functional group tolerance, good to high yields, and easy recyclability of the palladium catalyst. The reaction is the first example of heterogeneous palladium-catalyzed carbonylative coupling for the preparation of diverse 2-arylbenzoxazinones from commercially easily available 2-iodoanilines and aryl iodides.
From Methaqualone and Beyond: Structure - Activity Relationship of 6-, 7-, and 8-Substituted 2,3-Diphenyl-quinazolin-4(3H)-ones and in Silico Prediction of Putative Binding Modes of Quinazolin-4(3H)-ones as Positive Allosteric Modulators of GABAA

Quinazoline derivatives are heterocyclic compounds that acts as important structural lead for the discovery of effective therapeutic agents. The anti-inflammatory activity along with cytotoxicity helps to reduce the inflammation and pain associated with carcinoma. Derivatives of quinazoline-4-one were preliminary screened and in silico molecular modelling studies using Autodock were performed. In the docking study, ligands were docked against anticancer and anti-inflammatory targets. In silico analysis revealed that the compounds with aromatic substitution at 3rd and halogen substitution at 6th or 7th positions possess lesser side effects and have more potent antitumor activity. Based upon these results 12 compounds were selected, synthesized, characterized and screened for their in vitro, anti-inflammatory, antioxidant and anticancer activities. From the in vitro studies, compounds QA4, QA7 and QB1 showed good anticancer, anti-inflammatory and antioxidant activity when compared to the standard.
