Use of 2-(methoxycarbonyl)phenyllead triacetate in lactone synthesis

Reactions of 2-(methoxycarbonyl)phenyllead triacetate with β-oxo lactones and phenols in the presence of pyridine afforded polycyclic lactones in good yields. A one-pot three-step synthesis without isolation of intermediate products was developed.

Pd(II)-Catalyzed Oxidative Annulation via Double C-H Activations: Synthesis and Photophysical Properties of Bis-Coumarins

A Pd(II)-catalyzed oxidative annulation reaction of 4-hydroxycoumarin and arylcarboxylic acid via double C-H bond activations has been accomplished for the synthesis of bis-coumarins. This synthetic strategy provides a wide range of structurally diversified bis-coumarins in moderate to good yields with a variety of functional group compatibility. Moreover, photophysical properties of synthesized bis-coumarins have been evaluated, which reveals their interesting fluorescent properties.

Rh(III)-Catalyzed Diverse C—H Functionalization of Iminopyridinium Ylides

Divergent synthesis of useful skeletons has been realized via rhodium(III)-catalyzed C—H activation of iminopyridinium ylides and coupling with various unsaturated coupling reagents. Isocoumarins and isoquinolones were obtained via cleavage of the C—N or

Harnessing hypervalent iodonium ylides as carbene precursors: C-H activation of: N -methoxybenzamides with a Rh(iii)-catalyst

Hypervalent iodonium ylides expeditiously generate carbenes which undergo domino intermolecular C-H activation followed by intramolecular condensation in the presence of N-methoxybenzamide as a starting material and a Rh(iii)-catalyst to afford dihydrophenanthridines. KIE studies and DFT calculations were performed to substantiate the mechanistic pathway. To extend the synthetic utilisation, fluorescent pyranoisocoumarins were achieved by using Rh(iii)-catalyzed peri-C-H/O-H activation/annulation reactions.

Method for preparing 5, 12-dioxoanthracene-6, 11-diketone compound through nickel catalysis

The invention discloses a method for preparing a 5, 12-dioxoanthracene-6, 11-diketone compound through nickel catalysis. The preparation method comprises the following steps: a 2-hydroxyphenyl allyl propionic acid compound and a 2-halogenated benzoic acid compound fully react under the promotion of N, N-dimethylformamide (DMF) serving as a medium, nickel tetracarbonyl serving as a catalyst and sodium ethoxide serving as alkali to obtain a target product, and the product is subjected to aftertreatment to obtain the 5, 12-dioxoanthracene-6, 11-diketone compound. In the reaction formula, R1 is selected from one of hydrogen, methyl and methoxyl; R2 is selected from one of hydrogen and methyl; and X (halogen) is selected from one of bromine and iodine. According to the method, nickel is adoptedas a catalyst, and efficient preparation of the 5, 12-dioxoanthracene-6, 11-diketone compound is achieved. The method has the advantages of high catalytic efficiency, low substrate cost, simple operation, low equipment requirement, excellent yield and the like.
