Palladium-catalyzed cross-coupling reactions between carboxylic acids and aryl halides have several possible competitive pathways. Decarboxylative C-C bond coupling and C-H arylation are well established in the literature. However, direct C-O bond coupling between carboxylic acids and aryl halides has received little success. In this report, we describe a protocol for exclusive C-O bond formation, enabled by a bidentate N,N-ligand such as 1,10-phenanthroline. The reaction is general for a broad range of carboxylic acids and iodoarenes. Experimental evidence and computational results suggest a high energy barrier for the alternative pathway of decarboxylative carbon-carbon bond coupling.

(-)-5-Hydroxygoniothalamin, (-)-5-acetylgoniothalamin, and (+)-5-hydroxygoniothalamin, isolated from the Goniothalamus genus, are synthesized from triacetyl-O-D-glucal by employing the Ferrier reaction, Mitsunobu reaction, and Jones oxidation as key steps. The synthetic procedure also yields the epimers of (-)-5-hydroxygoniothalamin and (+)-5-hydroxygoniothalamin employing acid-mediated transition-metal-free epimerization at C-5 of styryllactones. Further studies reveal that the epimerization is facilitated by the phenyl group present on the styryllactones. Also, depending on the dihydroxylation reaction conditions, various analogues of saturated styryllactones are synthesized utilizing oxa-Michael reaction conditions.

Enantioselective formation of cyclohexene derivatives bearing an all-carbon quaternary stereogenic center is described. The racemic cyclohexenes are readily transformed to chiral substituted cyclohexenes in good yield with excellent enantioselectivity and diastereoselectivity by a palladium-mediated deracemization. The resulting products are promising synthetic intermediates of biologically active natural products. This protocol provides us with a new entry to the concise and scalable synthesis of multifunctionalized compounds.

Modifying the surface of metal catalyst is a crucial subject for improving the heterogeneous metal catalysts. It is still a great challenge to understand the structure-activity relationship (SAR) between the surface supporting groups and the metal particles. Herein, Rh NPs supported on the magnetic silica sphere with various functional groups (-NH2, -SH, -SO3H, -N=CH2, -Cl, -NHCOCH3 and -NHCH2Ph) have been prepared for catalytic hydrogenation of nitroarenes under atmospheric pressure at room temperature. We discover that the chemical state of Rh NPs depends on the supporting groups significantly. The electron-donating functionalities can effectively elevate the Rh-0/Rh3+ ratio, which increase the catalytic performance both in conversion and selectivity. The amino group decorated catalyst has such a good selectivity that no dechlorination reaction is observable in the hydrogenation of 2-chloro-3-nitropyridine. What’s more, by introducing magnetic Fe3O4 nuclei and mesoporous silica encapsulating layer, the catalyst can be recovered conveniently by an external magnet, and can be reused 10 cycles without any loss of activity.

Poisonous weeds are a global problem since they not only hinder local economic development, but also cause ecological harm. Consolida rugulosa (family Ranunculaceae) is a weed that is widespread in Northwestern China and causes severe poisoning when ingested by livestock. In the present study, we purified the toxins in this plant and investigated their mechanism of action. Five natural diterpene alkaloids (compounds 1-5)-including two new compounds (1 and 2)-were isolated, and five semi-synthetic derivatives (6-10) were synthesised based on 4 or 5 for structure-activity analysis. The toxicity of the compounds was evaluated in vitro with lactate dehydrogenase (LDH) assay. All of the compounds-especially 1-stimulated LDH release in primary cultured rat myocardial cells, an effect that was blocked by the Na+ channel blocker lidocaine. Electrocardiography revealed that rats treated with 1 had severe arrhythmia, while heart Doppler echocardiography and analysis of serum biomarkers levels revealed that administration of 1 for 15 days induced changes in cardiac structure and myocardial enzyme levels. These effects were antagonised by lidocaine treatment. Thus, diterpene alkaloids are the main compounds responsible for the cardiotoxicity of C. rugulosa, which can be mitigated by co-administration of lidocaine.

A site-selective supported palladium nanoparticle catalyzed Suzuki-Miyaura cross-coupling reaction with heteroaryl esters and arylboronic acids as coupling partners was developed. This methodology provides a heterogeneous catalytic route for aryl ketone formation via C(acyl)-O bond activation of esters by successful suppression of the undesired decarbonylation phenomenon. The catalyst can be reused and shows high activity after eight cycles. The XPS analysis of the catalyst before and after the reaction suggested that the reaction might be performed via a Pd-0/Pd-II catalytic cycle that began with Pd-0.

Equations for vapor pressure VP, as log VP, at 298.15 K for a set of 1016 liquid organic and organometallic compounds have been constructed using Abraham descriptors. The regression standard deviations of 0.28 and 0.31 log units are excellent by comparison with literature values for large data sets. Similar equations for a set of 359 solid organic and organometallic compounds were very poor, but if carboxylic acids were excluded we obtained equations for 261 compounds with standard deviations of 0.62 and 0.66 log units. For the 98 carboxylic acids taken separately we obtained equations with standard deviations of 0.84 and 0.91 log units. Equations for the carboxylic acids were substantially different to those that excluded carboxylic acids, due, we suggest, to the particular dimeric structure of the crystalline carboxylic acids.

The catalytic activity of two types of L-prolinamide organocatalysts was investigated for asymmetric Michael addition reaction of cyclic/acyclic ketones with beta-nitrostyrens. L-Prolinamides bearing amino groups on phenyl ring worked well, though their catalytic efficiency as well as selectivity was found to be dependent upon the position of amine group to the amide bond. Organocatalyst having -NH2 group ortho to amide bond provided the best results. Substrate scope was also studied by performing the reaction of various beta-nitrostyrenes with ketones to afford the corresponding Michael adducts in excellent yields with very high diastereoselectivities and enantioselectivities in almost all cases.
