New enediyne derivatives: Synthesis of symmetrically and unsymmetrically disubstituted 4,5-dialkynyl-3(2H)-pyridazinones

4,5-Dialkynyl-2-(methyl or phenyl)-3(2H)-pyridazinones (2a-c) were efficiently prepared via Sonogashira cross-coupling reaction on 4,5-dichloro-2-(methyl or phenyl)-3(2H)-pyridazinones (1a,b). Selective Sonogashira reactions were successfully achieved on 4-chloro-2-methyl-5-trifluoromethanesulfonyloxy- (6) and 5-chloro-2-methyl-4-trifluoromethanesulfonyloxy-3(2H)-pyridazinone (11), yielding 5-alkynyl-4-chloro- (7a-c) and 4-alkynyl-5-chloro-2-methyl-3(2H)-pyridazinones (3a,c,e), respectively. Compounds 7a-c and 3a,c,e were subjected to a second Sonogashira reaction giving 4,5-dialkynyl-2-methyl-3(2H)-pyridazinones (8a-c) bearing two different acetylene substituents. Suzuki cross-coupling reaction was also achieved on compounds 7a and 3a producing 4-aryl-5-phenylethynyl- and 5-aryl-4-phenylethynyl-2-methyl-3(2H)-pyridazinones, respectively, in excellent yield.

Discovery and structure-activity relationship analysis of Staphylococcus aureus sortase A inhibitors

Methicillin resistant Staphylococcus aureus (MRSA) is a major health problem that has created a pressing need for new antibiotics. Compounds that inhibit the S. aureus SrtA sortase may function as potent anti-infective agents as this enzyme attaches virulence factors to the cell wall. Using high-throughput screening, we have identified several compounds that inhibit the enzymatic activity of the SrtA. A structure-activity relationship (SAR) analysis led to the identification of several pyridazinone and pyrazolethione analogs that inhibit SrtA with IC50 values in the sub-micromolar range. Many of these molecules also inhibit the sortase enzyme from Bacillus anthracis suggesting that they may be generalized sortase inhibitors.

One-pot synthesis of [1,2,3]triazole-fused pyrazinopyridazindione tricycles by a ‘click and activate’ approach

Substituted [1,2,3]triazole-fused pyrazinopyridazindione tricycles were synthesized in a four-component, stepwise condensation. The key step in this one-pot process was a thermal [3+2] triazole formation which activated the adjacent position and set the stage for a subsequent tandem nucleophilic aromatic substitution/cyclization sequence.

Synthesis of novel fused azecine ring systems through application of the tert-amino effect

Novel fused azecine ring systems were synthesized via the microwave-assisted thermal isomerization of terphenyl or biphenyl-pyridazine compounds possessing a vinyl and a tert-amino group, through application of a new extension of the tert-amino effect. Substrates for the ring closure were prepared from ortho-dihalobenzene or pyridazinone by consecutive Suzuki couplings with ortho-sec-amino- and formylphenylboronic acids, followed by Knoevenagel condensation of the aldehydes obtained.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 1698-53-9, you can also check out more blogs about1698-53-9
