Marine-derived species, in particular, fungi, algae, sponges, and coelenterates are fertile grounds for the discovery of biologically and pharmacologically potent compounds. These molecules are structurally unique and possess a wide range of pharmacological activities. The rigid spiroacetal framework, that is, tetrahydro-spirofurofuranones is present in cephalosporolides E, F, H, and I, while the macrolactone structure is exemplified by cephalosporolides B, C, D, G, and J. These marine-derived molecular architectures are appealing to the synthetic community for their stereoselective synthesis. The present review represents a comprehensive overview of all the reported syntheses of these marine-derived molecules.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Catalyst tune-up: A readily available, air-stable amino-sulfide catalyst, [RuCl2(PPh3){HN(C2H4SEt) 2}], has been developed. This complex displays outstanding efficiency for the hydrogenation of a broad range of substrates with C-X bonds (esters, ketones, imines), as well as for the acceptorless dehydrogenative coupling of ethanol to ethyl acetate (see scheme).

Exchange etherification of dicarbonylcyclopentadienyl(eta2-ethyl vinyl ether)iron tetrafluoroborate (4) with optically active primary and secondary alcohols yields a mixture of diastereomeric cations.These isomers are in rapid equilibrium at room temperature.The most favorable equilibrium ratio of such diastereomers (4:1) is achieved with (+)- or (-)-menthol, and the absolute configuration of the predominant diastereomer, formed with (-)-menthol, has been determined.Optically active dicarbonylcyclopentadienyl (eta2-olefin)iron tetrafluoroborate may also be prepared from optically active epoxides.A study of the circular dichroism of these optically active complexes, together with those prepared earlier from the dioxene-iron complex (1), has been carried out and a mechanism by which asymmetry is induced at the achiral metal center is proposed.These observations provide the basis for a quadrant rule relating the sign of the Cotton effect near 450 nm and the absolute configuration of the olefin-iron complex.

We describe efficient and flexible enantioselective syntheses of the active enantiomers of the pheromones of pine sawflies, including the species Diprion jingyuanensis, their homologs and, stereoisomers, as well as those identified from the Chinese species Diprion jingyuanensis, i.e., 126. A total of 48 compounds, including acetates 78-101 and propanoates 102-125, have been synthesized. Our general approach towards these compounds originated from the commercially available chirons diethyl (S)- and (R)-malates, as well as ethyl (R)-3-hydroxybutanoate.

Chemistry involves the study of all things chemical – chemical processes, chemical compositions and chemical manipulation – in order to better understand the way in which materials are structured, how they change and how they react in certain situations. Application of 4254-15-3,

Monoclonal antibodies (mAbs) were generated against the coplanar transition state (TS(paragraph)) analogue 1 and assayed for their ability to catalyze the isomerization of bridged biphenyls 4, 6, and 7. This is a relatively simple unimolecular reaction whose activation barrier arises from unfavorable steric interactions between the two benzylic methylene groups and strain in the bridging ring system. Seven mAbs were found that catalyzed the isomerization of 4 to 6; the most efficient (mAb 64D8E10) has k(cat) and K(M) values of 4.3 x 10-5 s-1 and 420 muM, respectively. This corresponds to a rate enhancement over the unimolecular uncatalyzed reaction (k(cat)/k(uncat)) of 2900. The dissociation constant for the TS(paragraph) analogue, K(d), was determined to be 210 nM. For both the antibody (64D8E10) catalyzed and uncatalyzed reactions, the free energy of activation (DeltaG(paragraph)) is comprised largely of the enthalpy term; the antibody decreases the enthalpy of activation by 5 kcal/mol. Despite relatively large differences in the values of k(cat)/k(uncat) for the five antibodies, the ratios of K(d) to K(M)(4) are very similar. It is likely that the antibodies catalyze this reaction by reducing both ring strain and nonbonded steric interactions in the transition state.

In a Article，once mentioned of 19132-06-0

Synthetically versatile conjugate addition of a range of carbon, nitrogen, oxygen, sulfur and selenium nucleophiles to the highly functionalised 2-thio-3-chloroacrylamides is described. The stereochemical and synthetic features of this transformation are discussed in detail. In most instances, the nucleophile replaces the chloro substituent with retention of stereochemistry. With the oxygen nucleophiles, a second addition can occur leading to acetals, while with the nitrogen nucleophiles, E-Z isomerism occurs in the resulting enamine derivatives. The ratio of the E/Z isomers can be rationalised on the basis of the substituent and the level of oxidation.

Alkali metals dissolve in amines and ethers to give visible and infrared absorption bands.The visible band is believed to be due to absorption by the alkali metal anion and the infrared band to absorption of light by the solvated electrons.The visible and circular dichroism spectra of sodium-potassium alloy dissolved in several optically active ethers and amines were examined.In all cases, no circular dichroism could be detected corresponding to the alkali anion transition.An excellent synthetic route for the formation of a variety of chiral polyethers and cyclic polyethers is described.The method uses the readily available, chiral ethyl (S)-(+)-lactate.
