Article Abstract

In this study, we present a series of theoretically designed B2G14G14' molecules, featuring four-membered-ring heterocycles containing boron and heavy group 14 elements (G14 and G14' = Si, Ge, Sn, and Pb). Through the use of density functional theory (DFT), natural bond orbital (NBO) analysis, quantum theory of atoms in molecules (QTAIM), and electron localization function (ELF), our studies demonstrate a strong π single bond between the bridgehead G14 and G14' atoms, with minimal participation from a very weak G14-G14' σ bond. Additionally, the nucleus independent chemical shift (NICS), anisotropy of current-induced density (ACID), and adaptive natural density partitioning (AdNDP) analyses definitively establish the presence of both σ-aromaticity and π-aromaticity in these inorganic four-membered heterocyclic neutral molecules.

Harnessing Oxetane and Azetidine Sulfonyl Fluorides for Opportunities in Drug Discovery.

Four-membered heterocycles such as oxetanes and azetidines represent attractive and emergent design options in medicinal chemistry due to their small and polar nature and potential to significantly impact the physiochemical properties of drug molecules. The challenging preparation of these derivatives, especially in a divergent manner, has severely limited their combination with other medicinally and biologically important groups. Consequently, there is a substantial demand for mild and effective synthetic strategies to access new oxetane and azetidine derivatives and molecular scaffolds.

Palladium catalyzed ortho-C(sp)-H activation/cyclization of aryl amines assisted by imine and vinylacetic acid.

Nat Commun

Palladium-catalyzed directed C - H functionalization/cyclization is an effective approach for synthesizing nitrogen heterocycles. Imine, known for its ease of installation/removal, has been extensively used in the C-H activation of aldehydes, ketones, and alkylamines. Nevertheless, it has been rarely explored in the C(sp)-H activation of aryl amines because of the generation of a strained four-membered palladacycle.

Frustrated Alternative Approaches towards the Synthesis of a Thermally Stable 1,2-Diazacyclobutene.

Molecules

Department of Chemistry and Biochemistry, Berry College, 2277 Martha Berry HWY, Mount Berry, GA 30149, USA.

We have previously demonstrated that an appropriately substituted four-membered-ring 1,2-diazacyclobutene is a useful compound in organic synthesis for the introduction of strained 1,2-diazetidine rings. In order to further explore the reactivity of this interesting heterocycle, we sought a method to improve upon the poor synthetic yield reported earlier. A novel route involving the synthesis of a similarly substituted 1,2-diazetidine compound followed by free-radical bromination and base-catalyzed debromination appeared promising.

An effective synthesis strategy for the preparation of 1'-spiro[indene-1,2'-quinoxaline] has been developed. This involves a Rh(III)-catalyzed [3 + 2]-annulation of quinoxalines with alkynylcyclobutanols. The developed protocol offers a straightforward method for the preparation of versatile heterocyclic compounds with a four-membered ring and is compatible with a wide range of functional groups.
