- Br?nsted acid-catalysed conjugate addition of photochemically generated α-amino radicals to alkenylpyridines
-
The conjugate addition of α-amino radicals to alkenylpyridines has been accomplished by the synergistic merger of Br?nsted acid and visible light photoredox catalysis. Key to reaction development was the protonation of the alkenylpyridines that transientl

- Preparation method of 2-styrylbenzoxazole derivatives and application of 2-styrylbenzoxazole derivatives in anti-tumor effect
-
The invention discloses a structure and preparation method of 2-styrylbenzoxazole derivatives. 2-styrylbenzoxazole and different substituted aromatic aldehydes are taken as raw materials to react in one step under the anhydrous and oxygen-free conditions and the action of potassium tert-butoxide to generate 2-styrylbenzoxazole heterocyclic compounds. The preparation method has the advantages of being simple in reaction step, short in reaction time, good in selectivity and the like. In addition, the invention further provides research on application of an anti-tumor effect. The compounds 1, 2, 3 and 4 all show the certain bioactivity on in-vitro HepG2 cell proliferation inhibition, wherein the inhibition rate of the compound 1 on in-vitro HepG2 cell proliferation under the 100 micrometer concentration reaches 85.4%, and the inhibition rate of the compound 4 on in-vitro HepG2 cell proliferation under the 100 micrometer concentration reaches up to 93.4%.

- Ligand promoted Pd-catalyzed dehydrogenative alkenylation of hetereoarenes
-
An efficient Pd-catalyzed cross-dehydrogenative coupling of heteroarenes with styrenes and other olefinic substrates has been developed. This alkenylation paradigm encompasses a wide range of substrates and provides a straightforward approach toward C2-E-alkenylated azole motifs. This journal is the Partner Organisations 2014.
