Palladium-Catalized Oxidative Cyclization of 1,5-Dienes. Influence of Diferent Substitution Patterns on the Regio- and Stereochemistry of the Reaction

Oxidative cyclization of 1,5-dienes in acetic acid in the presence of the Pd(II) regenerating catalyst system Pd(OAc)2/MnO2/p-benzoquinone has been shown to yield, depending on the structure of the 1,5-diene, acetoxyexomethylenecyclopentanes or acetoxyvinylcyclopentanes. 1,5-Dienes with substituents in the 1- and/or 3-position show a high preference for formation of regioisomers obtained by acetate attack at the sterically least hindered double bond, but the products are usually mixtures of diastereomeric cis and trans ccyclopentanes. trans-1-Phenyl-1,5-hexadienes react with complete stereoselectivity to yield exomethylenecyclopentanes with a single configuration of the exocyclic double bond.The oxidative cyclization method is synthetically useful, affording a large variety of cyclopentane systems.

Semi-synthesis and insecticidal activity of spinetoram J and its D-forosamine replacement analogues

Spinetoram, a mixture of spinetoram J (XDE-175-J, major component) and spinetoram L (XDE-175-L), is a new kind of fermentation-derived insecticide with a broad range of action against many insect pests, especially Cydia pomonella, Leaf miner and Thrips. Similar to spinosad, spinetoram is friendly to the environment, and non-toxic to animals and human beings. Therefore, spinetoram has been widely applied in pest control and grain storage. In a previous study, we had reported a semi-synthesis of spinetoram J. However, in that synthesis, there were more experimental steps, and the operations were troublesome. So an improved synthesis based on a self-protection strategy was designed and discussed. In this work, 3-O-ethyl-2,4-di-O-methylrhamnose was used as both the reaction substrate of C9?OH and the protecting group of C17?OH. The number of synthetic steps and costs were significantly reduced. In addition, a variety of D-forosamine replacement analogues of spinetoram J were synthesized based on the improved semi-synthesis, and their insecticidal activities were evaluated against third-instar larvae of Plutella xylostella. Although none of the analogues were as potent as spinetoram, a few of the analogues have only a 20?40 times lower activity than spinetoram. In particular, one of these analogues was approximately as active as spinosad. This study highlights the possibility of developing new insecticidal chemistries by replacing sugars on natural products with other groups, and the improved semi-synthesis will be helpful for further researches on spinetoram.

Ruthenium complexes with N-functionalized secondary amino ligands: a new class of catalysts toward efficient hydrogenation of esters

A series of ruthenium complexes (o-PPh2C6H4NHR)2RuCl2 (R = Me, 3; Et, 4; CH2Ph, 5) and (o-PPh2C6H4NH2)[(CH2NHR)2]RuCl2 (R = Me, 7; Et, 8; iPr, 9) modulated with mono-N-functionalized secondary amino ligands were synthesized and demonstrated as efficient catalysts in the hydrogenation of esters into alcohols. The catalytic performances of these new complexes are much better than their corresponding primary amino ligand-constituted complexes (o-PPh2C6H4NH2)2RuCl2 (2) and (o-PPh2C6H4NH2)[(CH2NH2)2]RuCl2 (6). The significant improvement is attributed to the increased electron density of the secondary amino ligand in comparison with that of the primary amino ligand.

Discovery, synthesis and characterization of a series of (1-alkyl-3-methyl-1H-pyrazol-5-yl)-2-(5-aryl-2H-tetrazol-2-yl)acetamides as novel GIRK1/2 potassium channel activators

The present study describes the discovery and characterization of a series of 5-aryl-2H-tetrazol-3-ylacetamides as G protein-gated inwardly-rectifying potassium (GIRK) channels activators. Working from an initial hit discovered during a high-throughput screening campaign, we identified a tetrazole scaffold that shifts away from the previously reported urea-based scaffolds while remaining effective GIRK1/2 channel activators. In addition, we evaluated the compounds in Tier 1 DMPK assays and have identified a (3-methyl-1H-pyrazol-1-yl)tetrahydrothiophene-1,1-dioxide head group that imparts interesting and unexpected microsomal stability compared to previously-reported pyrazole head groups.

Practical preparation of lacto-N-biose I, a candidate for the bifidus factor in human milk

A one-pot enzymatic reaction to produce lacto-N-biose I (LNB), which is supposed to represent the bifidus factor in human milk oligosaccharides, was demonstrated. Approximately 500mM of LNB was generated in 10-liter of reaction mixture initially containing 660 mM of sucrose and 600mM of GlcNAc by the concurrent actions of four enzymes, sucrose phosphorylase, UDP-glucose – hexose-1-phospate uridylyltransferase, UDP-glucose 4-epimerase, and lacto-N-biose phosphorylase, in the presence of UDP-Glc and phosphate, indicating a reaction yield of 83%. LNB was isolated from the mixture by crystallization after yeast treatment. Finally, 1.4 kg of LNB of 99.6% purity was recovered after recrystallization.
