22.11.2021 · Asymmetric construction of dithiodiketopiperazines on otherwise achiral scaffolds remains a pivotal synthetic challenge encountered in many biologically significant natural products. Herein, we report the first total syntheses of (−)-glionitrin A/B and revise the absolute configurations. Emerging from the study is a novel oxidative sulfenylation of triketopiperazines …

Oct 19, 2021 · Gui and co-workers report the first total synthesis of (+)-clionastatins A and B, a novel class of polyhalogenated steroids isolated from a natural source. The synthesis led to revision of the originally proposed structures. # Comment. Acyl telluride C was accessed in three steps from enone A.

18.11.2020 · Interconversion of dankasterone B and periconiastone A was observed. Abstract We describe herein the assembly of the cis -decalin framework through radical cyclization initiated by metal-catalyzed hydrogen atom transfer (MHAT), further applied it in the asymmetric synthesis of dankasterones A and B and periconiastone A. Position-selective C−H oxygenation allowed for …

12.07.2021 · Herein we report the first total synthesis of polychlorinated steroids clionastatins A and B, which was accomplished asymmetrically by means of a convergent, radical fragment coupling approach. Key features of the synthesis include an Ireland–Claisen rearrangement to introduce the C5 stereocenter (which was ultimately transferred to the C10 quaternary …

24.08.2021 · Total Synthesis of Clionastatins A and B. Clionastatins A and B (pictured, X = H for clionastatin A, X = Cl for clionastatin B) are polychlorinated steroids that were first isolated from the sponge Cliona nigricans. Their proposed structure has been based on NMR spectroscopic data, and no X-ray crystallographic structures have been available.
