Schmidt, Ulrike; Theumer, Gabriele; Jaeger, Anne; Kataeva, Olga; Wan, Baojie; Franzblau, Scott G.; Knoelker, Hans-Joachim published the artcile< Synthesis and activity against Mycobacterium tuberculosis of olivacine and oxygenated derivatives>, HPLC of Formula: 56724-03-9, the main research area is olivacine oxygenated derivative preparation antitubercular; catalysis; cyclization; inhibitory activity; olivacine; palladium; pyrido[4,3-b]carbazoles.

The tetracyclic pyrido[4,3-b]carbazole olivacine I and its four oxygenated derivatives have been synthesized by a late-stage palladium-catalyzed Heck-type cyclization of the pyrrole ring as a key step. All the final compounds were evaluated for their antitubercular activity. In a test for the inhibition of the growth of Mycobacterium tuberculosis, 9-methoxyolivacine showed the most significant inhibitory activity against Mycobacterium tuberculosis, with an MIC90 value of 1.5 μM.

Plamondon, Samuel J.; Warnica, Josephine M.; Kaldre, Dainis; Gleason, James L. published the artcile< Hydrazide-Catalyzed Polyene Cyclization: Asymmetric Organocatalytic Synthesis of cis-Decalins>, Product Details of C9H10O2, the main research area is hydrazide polyene enantioselective diastereoselective cyclization catalyst; decalin stereoselective preparation; asymmetric catalysis; cis-decalin; hydrazide; organocatalysis; polyene cyclization.

Polyene cyclizations offer rapid entry into terpenoid ring systems. Although enantioselective cyclizations of (E)-polyenes to form trans-decalin ring systems are well precedented, highly enantioselective cyclizations of (Z)-polyenes to form the corresponding cis-decalins have not been reported. Here, we describe the first application of iminium catalysis to the initiation of polyene cyclizations. Et 1,2-diazepane-1-carboxylate catalyzes the cyclization of polyenes bearing enal initiators. Moreover, chiral bicyclic hydrazides catalyze the cyclizations of (Z)-polyene substrates to form cis-decalins with enantioselectivities of up to 97:3 er. DFT calculations suggest the catalysts promote the reaction by stabilizing pos. charge as it develops during the bicyclization.

Dickschat, Jeroen S.; Wang, Tao; Stadler, Marc published the artcile< Volatiles from the xylarialean fungus Hypoxylon invadens>, Electric Literature of 56724-03-9, the main research area is Hypoxylon fungal volatile natural product constitutional isomer; constitutional isomerism; gas chromatography; mass spectrometry; natural products; volatiles.

The volatiles emitted by agar plate cultures of the xylarialean fungus Hypoxylon invadens were investigated by use of a closed loop stripping apparatus in combination with GC-MS. Several aromatic compounds were found that could only be identified by comparison to all possible constitutional isomers with different ring substitution patterns. For the set of identified compounds a plausible biosynthetic scheme was suggested that gives further support for the assigned structures.

Urakawa, Kazuki; Kawabata, Yuta; Matsuda, Masaki; Sumimoto, Michinori; Ishikawa, Hayato published the artcile< α-Ketocarbenium Ions Derived from Orthoquinone-Containing Polycyclic Aromatic Compounds>, Computed Properties of 56724-03-9, the main research area is keto carbenium ion preparation orthoquinone PAH absorption spectra.

α-Ketocarbenium ions derived from synthesized orthoquinone-containing polycyclic aromatic compounds were generated in the presence of Bronsted acids such as sulfuric acid, trifluoromethanesulfonic acid, and fluorosulfonic acid. The prepared α-ketocarbenium ions were stabilized by conjugation of the aromatic moiety. In addition, unique absorption properties of the α-ketocarbenium ions were observed and identified on the basis of the calculated absorption spectra. It was suggested that the zigzag-shaped architecture stabilizes the newly discovered α-ketocarbenium ions derived from orthoquinone-containing polycyclic aromatic compounds
