Synthesis of naphthalene ring derivatives and Benzoheterocycles the method of the compound
-
Paragraph 0062; 0063, (2016/10/10)
The invention discloses a method for synthesizing naphthalene derivative and benzo-heterocycle compounds. The method is realized by promoting a reaction similar to Mortia-Baylis-Hillman between aryl aldehyde having alpha, beta-unsaturated ester on ortho-position and ketone compounds under the catalysis action of tertiary amine and tertiary phosphine organic small molecular catalysts, so as to remove a molecule of H2O, so that the naphthalene derivative or benzo-heterocycle compounds are generated. The method disclosed by the invention is simple in operation step, cheap and easily available in adopted catalysts and harmless to environment, and a series of naphthalene derivative and benzo-heterocycle compounds are synthesized with relatively high yield.

An environmentally benign [Cu(I)]-catalyzed oxidation of activated (benzylic/allylic) alcohols to the corresponding carbonyl compounds is presented. Interestingly, the reaction was also compatible with benzylic alcohols containing ortho-bromo substituents on the aromatic ring without competing with the expected intermolecular Buchwald coupling. Significantly, the catalytic system enables the synthesis of cinnamate-esters in a sequential domino one-pot fashion via oxidation followed by Wittig-Horner protocol. Copyright

A series of new bromophenols and chlorophenols were prepared by a practical route. The in vitro antioxidative activity of the halophenols was evaluated by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical-scavenging assay, and their cytoprotective activity was also tested on hydrogen peroxide (H2O2)-induced injury in human umbilical vein endothelial cells (HUVEC). All halophenols tested displayed moderate to good DPPH radical-scavenging activity, and two bromophenols, 2,3′-dibromo-4,5,6′-trihydroxydiphenylmethanone (16c) and 2,3-dibromo-4,5-dihydroxydiphenylmethanone (17c) exhibited high protective activity against H2O2-induced injury in HUVEC with EC50 values of 0.4 and 0.8 μM, respectively. The preliminary structure-activity relationships of these compounds were also investigated in order to determine the essential structures required for their bioactivities.
