Abstract: A highly efficient synthesis of polycyclic amides by Rh(III)-catalyzed cascade cyclization of 3-phenyl-1, 4, 2-dioxazol-5-one and diphenylacetylene has been developed. This novel one-pot strategy expanded the application scope of directing groups to dioxazolones. read more here.

DOI: 10.1016/j.tetlet.2020.152128
Abstract: Abstract Using an isoindole umpolung strategy, a one-pot synthesis of polycyclic isoindolines was accomplished. In this reaction, the in situ-generated nucleophilic isoindoles were converted to electrophilic isoindoliums via protonation, which underwent a Pictet-Spengler-type cyclization to… read more here.

DOI: 10.1021/jacs.2c07517
Abstract: A new approach for synthesizing polycyclic heterofused 7-deazapurine heterocycles and the corresponding nucleosides was developed based on C–H functionalization of diverse (hetero)aromatics with dibenzothiophene-S-oxide followed by the Negishi cross-cooupling with bis(4,6-dichloropyrimidin-5-yl)zinc. This cross-coupling afforded a… read more here.

DOI: 10.1039/d1dt01361k
Abstract: Polycyclic iridaaromatic compounds are of great interest not only because of the contributions made in "aromatic chemistry", but also because of the possibility of improving the results of the applications of the corresponding organic analogues… read more here.

DOI: 10.1039/d2cc00167e
Abstract: An oxidative-decarboxylative intramolecular cyclisation of dipeptide derivatives is reported. This transformation is promoted by phenyl iodine(III) diacetate (PIDA) in combination with BF3·OEt2. The reaction gives access to a variety of valuable polycyclic N-heterocyclic scaffolds containing… read more here.
