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

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.

Shang, Gao; Liu, Duan; Allen, Scott E.; Yang, Qin; Zhang, Xumu published the artcile< Asymmetric hydrogenation of α-primary and secondary amino ketones: efficient asymmetric syntheses of (-)-arbutamine and (-)-denopamine>, Product Details of C11H16O2, the main research area is asym hydrogenation amino ketone rhodium catalyst; alc amino chiral preparation rhodium catalyst.

Two β-receptor agonists (-)-denopamine (I) and (-)-arbutamine (II) were prepared in good yields and enantioselectivities by asym. hydrogenation of unprotected amino ketones for the first time by using Rh catalysts bearing electron-donating phosphine ligands. A series of α-primary and secondary amino ketones, e.g. ArCOCH2NHR (Ar = Ph, 2-MeOC6H4, 2-naphthyl, R = Me; Ar = Ph, R = Et), were synthesized and hydrogenated to produce various 1,2-amino alcs., e.g. ArCH(OH)CH2NHR, in good yields and with good enantioselectivities. This Rh electron-donating phosphine-catalyzed asym. hydrogenation rep- resents one of the most promising and convenient approaches towards the asym. synthesis of chiral amino alcs.

The synthesis of a new series of 1β-methylcarbapenems, I (R = SO2Me, SO2Et, SO2NHEt, SO2NMe2, SO2NH-n-Pr, COMe, H, CONH2) having methoxyimine and substituted sulfonamide moieties is described. Their in vitro antibacterial activities against both Gram-pos. and Gram-neg. bacteria were tested and the effect of substituents on the pyrrolidine ring was investigated. A particular compound I (R = SO2NHMe) having (methylamino)sulfonamide moiety showed the most potent antibacterial activity.

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.
