	1. Decarboxylative (4+1) Oxidative Annulation of Malonate Monoesters with 2-Vinylpyridine Derivatives
	TANG Shan,GAO Xinlong,LEI Aiwen
	Chemistry 03 June 2016
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:A novel N-iodosuccinimide mediated decarboxylative (4+1) oxidative annulation between 2-vinylpyridine derivatives and malonate monoesters was developed. It offered a new way to construct indolizines derivatives by utilizing malonate monoesters as C1 unit. Alkyl 2,2-diiodoacetate was found to be the active reaction intermediate during the transformation.

	3. Diastereo- and Enantioselective Aldol Reaction of Isocyanoacetates with Aldehydes Catalyzed by Chiral Phase-Transfer Catalysts
	DIAO Ruichuan,LI Shen
	Chemistry 29 April 2016
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:A diastereo- and enantioselective aldol reaction of tert-butyl isocyanoacetate with aldehydes was realized under metal-free phase-transfer catalytic conditions. Key to success was the use of a free 9-OH-containing cinchona alkaloid-based quaternary ammonium salt bearing bulky and electron-withdrawing aryl groups on the N-benzyl moiety. This process tolerates both aromatic and aliphatic aldehydes, affording the corresponding chiral oxazoline products in diastereoselectivities up to 20:1 and enantioselectivities up to 78% ee.

	Abstract:A efficient 1,3-dipolar cycloaddition reaction between the new chiral cyclic nitrones and alkenes was studied. After the optimization of reaction conditions, a series of valuable chiral isoxazolidine products were prepared with high yields. The structre of the products was characterized by NMR, IR and HR Ms. In addition, according to the analysis of the reaction's transition state, the stereoselevtivity of this cycloaddition and the absolute configuration of cycloadducts was explained reasonably.

	Abstract:A series of star-shaped fluorescent molecules (2-5), employing 1,3,5-triphenoxybenzene as core and triarylamine as terminal groups, were synthesized through a facile three-step approach. The stability, solid state structure, and photophysical properties of 2-5 were investigated. In comparison with pristine triphenylamine, the present star-shaped compounds display the strong fluorescence with high fluorescence quantum yields up to 81.8 %. Besides, the influence of the aryls on the electronic properties of the resulting star-shaped molecules has been evaluated.

	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:A concise total synthesis of (±)-pisiferin has been accomplished from α-cycloiral via Suzuki coupling and F-C alkylation as key reaction in five steps with an overall yield of 16%. The feature of this concise strategy is using acetyl group to protect the phenol which could be deprotection in moderate condition to avoid the isomerization of target molecular. This work not only provides a strategy to approach the total synthesis of pisiferin itself but also serves as an additional correlation origin to which many related icetaxane-type diterpenes can be referred.

	Abstract:Phosphomolybdic acid supported on silica gel (PMA/SiO2) has been used for the catalysis of the three-component reactions of aldehydes, amines and allyltributylstannane with acetonitrile as the solvent at room temperature. The experimental parameters were optimized in the three-component reaction system. The obtained results showed the PMA/SiO2 showed its highly efficient nature for catalyzing the three-component reactions. were not found to induce a obvious reduction in the yield of the corresponding allylation reaction, regardless of aromatic aldehydes and amines containing electron-donating or electron-withdrawing groups in the aromatic ring that involve in the three-component reaction with Aromatic amines or aldehydes and allyltributylstannane. Our results indicated that this synthetic process has advantages of high yield, mild reaction conditions, environment benign and easy manipulation.

	Abstract:For its impressive antibiotic activity, Eaton's reagent has been extensively used to catalyze the synthesis of 4-quinolone derivatives, but the mechanism behind the reaction is still not clear till now. In this paper, a possible mechanism for this reaction is revealed by using the density functional theory (DFT) method, which is consistent with the experimental phenomenon, and the existing main and side reactions are also explained successfully.
