Synthetic studies on furanosteroids: Construction of the viridin core structure via diels-alder/ retro- diels-alder and vinylogous mukaiyama aldol-type reaction

The synthesis of the viridin class of furanosteroids core skeleton from the readily available 2,3-dihydro-4-hydroxyinden-1-one (6) is described. Our strategy was broken down into three parts: (1) Synthesis of functionalized alkyne oxazoles of type 5; (2) intramolecular Diels-Alder/retro-Diels-Alder reaction of 5 followed by tautomerization and elaboration of R to give silylated furanonaphthols 4 bearing an aldehyde side chain; and (3) annulation of ring A by intramolecular vinylogous Mukaiyama aldol-type cyclization. Two major challenges were faced in the last step: (i) furanonaphthol derivatives bearing a beta-hydroxyaldehyde functionality (R1 = OH) suffered from dehydration to the E-enal, which is geometrically incapable of cyclization, and (ii) the functionality at C17 had a strong influence on the conversion of 4 to 3, as exemplified by the failure of the free ketone (X = O) or its derivatives (X = H, OH; X = H, OAc) to cyclize. In the end, success was realized with the analogous C17-norketone (X = H, H).

166330-10-5, Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 166330-10-5, in my other articles.

Highly effective luminescence stemmed from thermally activated delayed fluorescence (TADF) and phosphorescence for the new four-coordinate copper(I) complexes containing N-heterocyclic carbene (NHC) ligands

The two four-coordinate N-heterocyclic carbene (NHC) copper(I) complexes, [Cu(Ph-BenIm-methylPy)(POP)]PF6 (1), and [Cu(Ph-Im-methylPy)(POP)]PF6 (2) Ph-BenIm-methylPy = 3-benzyl-1-(6-methyl-pyridin-2-yl)-1H-benzimidazolylidene, Ph-Im-methylPy = 3-benzyl-1-(6-methyl-pyridin-2-yl)-1H-imidazolylidene, POP = bis[2-diphenylphosphino]-phenyl)ether) have been synthesized and characterized. Those complexes exhibit blue to green emission with very high quantum yields and long excited-state lifetimes. The experimental results reveal that the origin of emissive state at room temperature occurs from the combination of TADF and phosphorescence in which phosphorescence predominates TADF, and the corresponding emissive mechanisms were discussed. To the best of our knowledge, the combined emissions with high quantum yield close to ca. 100% have not been previously reported in this library of the four-coordinate NHC-Cu(I) complexes.
