Intramolecular stereoselective annulation of o-cinnamyloxy chalcones provides two kinds of tricyclic benzofused cyclobutaoxepanones via the synthesized routes of DABCO/NBS (1,4-diazabicyclo[2.2.2]octane/N-bromosuccinimide)-mediated Baylis-Hillman type cyc

- AuCl3-Catalyzed Ring-Closing Carbonyl–Olefin Metathesis
-
Compared with the ripeness of olefin metathesis, exploration of the construction of carbon–carbon double bonds through the catalytic carbonyl–olefin metathesis reaction remains stagnant and has received scant attention. Herein, a highly efficient AuCl3-catalyzed intramolecular ring-closing carbonyl–olefin metathesis reaction is described. This method features easily accessible starting materials, simple operation, good functional-group tolerance and short reaction times, and provides the target cyclopentenes, polycycles, benzocarbocycles, and N-heterocycle derivatives in good to excellent yields.

- Natural Products as Sources of New Fungicides (I): Synthesis and Antifungal Activity of Acetophenone Derivatives Against Phytopathogenic Fungi
-
Several series of 45 acetophenone derivatives bearing various alkyl or benzyl substituents were conveniently synthesized and their structures characterized by 1H and 13C NMR spectroscopy, HRMS and single-crystal X-ray analysis. Their in vitro antifungal activities against a panel of phytopathogenic fungi were evaluated by mycelial growth rate assay. Of them, 12 derivatives (e.g., 3a-c, 4c and 4e) exhibited more potent antifungal effects on some phytopathogens than a commercial fungicide hymexazol as positive control. In particular, compound 3b with IC50 values of 10-19μg/mL was found to be the most active in this series and might be a potential lead structure for further optimization. The preliminary structure-activity relationship (SAR) studies of a series of acetophenones are also discussed. A series of acetophenone derivatives have been synthesized and tested for their antifungal activities. Of them 12 derivatives exhibited more potent antifungal effects on some phytopathogens than a positive control hymexazol. Especially, compound 3b (IC50=10-19μg/mL) was found to be the most active and might be a potential lead structure. The SAR of these acetophenones is also discussed.

- Regioselectivity in the intramolecular allyl transfer reaction catalysed by electrogenerated nickel complexes: Influence of metal ions
-
The intramolecular transfer of allyl moieties from substituted allyl aryl ethers to carbonyl groups has been studied by electrosynthesis, in a nickel-catalysed reaction. The influence of metal ions such as Mg2+, Zn2+ and Al3+ has been examined. Regioselectivity towards the branched isomer was better with Zn2+ than with Mg2+ ions, but it was higher in the absence of added metal ions.
