    Abstract The synthesis of thiazole-fused derivatives of tricyclic quinazolinones hitherto undescribed was successfully achieved by replacing anthranilic acid or its derivatives by isomeric polyfunctionalized benzothiazole analogues of anthranilic methyl esters. Some of the new heterocyclic systems are inspired by natural alkaloids such as mackinazolinone, deoxyvasicinone, and isaindigotone, showing interesting biological properties. The microwave-assisted method developed is a variant of the Niementowski reaction and was also applied to the synthesis of ring-extended rutaecarpine derivatives.

    Abstract Transition-metal-free direct arylation of C-H or N-H bonds is one of the key emerging methodologies that is currently attracting tremendous attention. Diaryliodonium salts serve as a stepping stone on the way to alternative environmentally friendly and straightforward pathways for the construction of C-C and C-heteroatom bonds. In this review, we emphasize the recent synthetic advances of late-stage C(sp2)-N and C(sp2)-C(sp2) bond-forming reactions under metal-free conditions using diaryliodonium salts as arylating reagent and its applications to the synthesis of new arylated bioactive heterocyclic compounds.

    Abstract The synthesis of trifunctional isomeric benzothiazoles derived from nitroanthranilic acids and their corresponding anthranilonitrile analogues is studied. Compared to previous work, the reaction sequence affords convenient access to hitherto undescribed 2-cyanobenzothiazoles. For further synthetic applications of these polyfunctional compounds, a hydrolysis–decarboxylation sequence is performed in an acidic medium (HCl or HBr), leading to an enlarged array of relevant building blocks.

    Abstract A modular synthetic method, involving a hydrothiolation, silylation, and fluoroalkylation, for the construction of highly functionalized fluoroalkyl sulfides has been developed. The use of aprotic polar solvents enables the additive-free chemoselective hydrothiolation of tetrafluoroethylene, trifluorochloroethylene, and hexafluoropropene with various thiols. The stepwise functionalization reactions convert the hydrothiolated intermediates into the tetrafluoroethyl sulfides in high efficiency. The method avoids the use of the environmental pollutant Halon-2402, which was employed as a building block in a reported synthetic route.

    Abstract A practical and sustainable photocatalyst-free protocol for photoinduced synthesis of perfluoroalkylated quinazolin-4(3 H )-ones is described starting from quinazolin-4(3 H )-ones. A wide range of substituted or fused-quinazolinones is found to be compatible, providing the corresponding mono- and bis-perfluoroalkylated compounds in moderate yields. This visible-light-mediated C–H perfluoroalkylation allows an environmentally friendly and straightforward access to an array of unprecedented functionalized quinazolinone scaffolds, presenting attractive features for drug discovery. Control experiments demonstrated that a radical mechanism is involved in the reaction mechanism.
