Abstract: In this study, 3,4-dihydro-12-aryl-1H-benzo[b]xanthene-1,6,11-(2H,12H)trione compounds were obtained through one-pot condensation of various substituted aromatic aldehydes, 2-hydroxy-1,4-naphthoquinone, and dimedone in the presence of Bi(OTf)3 as a green and reusable catalyst. The structural characterization of these novel… read more here.

DOI: 10.1021/acs.inorgchem.2c00819
Abstract: In this paper, a new Mn-based metal-organic framework [UoB-6] was obtained via a one-step ultrasonic irradiation method with the ligand (H2bdda: 4,4'-(1,4-phenylenebis(azaneylylidene))bis(methaneylylidene))dibenzoic acid. The structural integrity of the synthesized BioMOF-Mn was corroborated by FT-IR, EDX,… read more here.

DOI: 10.1021/acs.orglett.3c01185
Abstract: An efficient electrochemical dehydrogenative cross-coupling of benzylic C-H bonds with 1-thiosugars at room temperature is described. The direct S-glycosylation protocol avoids using any oxidant, which provides facile access to various glycosylated xanthene derivatives with up… read more here.
