Construction of cyclic enones via gold-catalyzed oxygen transfer reactions
During the last decade, gold-catalyzed reactions have become a tour de force in organic synthesis. Recently, the gold-, Brønsted acid- or Lewis acid-catalyzed oxygen transfer from carbonyl to carbon-carbon triple bond, the so-called alkyne-carbonyl metathesis, has attracted much attention because this atom economical transformation generates α,β-unsaturated carbonyl derivatives which are of gre...
متن کاملSynthesis and analgesic activity of novel Hydrazide and Hydrazine derivatives
The uses of non-steroidal anti-inflammatory drugs (NSAIDs) are limited by a variety of side effects. So research on preparing new analgesic agents is important. According to some reports about the analgesic activity of hydrazide and hydrazine derivatives a new series of these compounds were synthesized in order to obtain new analgesic compounds. The final compounds 10a-10e and 15a-15d were pre...

متن کاملEvidence for two cyclic photophosphorylation reactions concurrent with ferredoxin-catalyzed non-cyclic electron transport
Addition of ferredoxin to isolated spinach chloroplast thylakoid membranes reconstitutes phosphorylating electron transfer characterized by elevated P / O ratios (1.6). When oxygen is the terminal electron acceptor for reduced ferredoxin, the P / O value is lowered by antimycin A or low concentrations (I0/~M) of heparin (an anionic macromolecule), but not by inhibition of the activity of membra...
