The synthesis of (+)-mesembrine (1) and (+)-mesembranol (2) has been achieved from the monoterpene (S)-(-)-perillyl alcohol. Key transformations include a diastereo- and regioselective Pd-mediated intramolecular Heck reaction, and a double reduction of the resultant cyclic sulfonamide, to afford the cis-3a-aryloctahydroindole skeleton.

Shape-persistent arylenevinylene macrocycles (AVMs) were successfully prepared in one step from readily available aromatic diene monomers through olefin metathesis in good yields. 1H NMR, UV-Vis absorption and fluorescence studies revealed the aggregation behavior of the obtained macrocycles. SEM characterization showed AVM nanofibril formation.

Ruthenium-indenylidene complexes represent a class of robust and efficient pre-catalysts for olefin metathesis reactions. In this feature article, we provide an overview of the various complexes belonging to this family and summarise their use in various applications. The relation between the nature of ancillary ligands around the metal coordination sphere of these complexes and their catalytic activity is also discussed. The Royal Society of Chemistry.

The (3S,5R) and (3R,5R) isomers of the title compound were synthesized from enantiopure epoxide chiral building blocks readily accessible from D-gluconolactone. The former (a syn-1,3-diol) gave 1H and 13C NMR spectroscopic data and optical rotation in good agreement with those reported for the natural product, whereas distinct differences were found with the data for the latter (an anti-1,3-diol). These results unambiguously showed that the absolute configuration of the natural product must be (3S,5R).

Metathesis condensation and isomerization reactions of allylic compounds were examined using Grubbs’ second-generation ruthenium catalyst [Ru*]. Allyl alcohol and allyl cyanide undergo metathesis condensation releasing ethylene, with conversions being the highest reported for these substrates. However, competing olefin isomerization rather than metathesis can occur under certain conditions when heteroatoms are present at the allylic position to the olefin.

The polyhydroxylated beta-amino acids (2S,3R,4S,5S,7E)-3-amino-8-phenyl- 2,4,5-trihydroxyoct-7-enoic acid (APTO) and (2S,3R,4S,5S,7E,9E)-3-amino-10-(4- ethoxyphenyl)-2,4,5-trihydroxydeca-7,9-dienoic acid (AETD) are key components of the microsclerodermin family of anti-fungal cyclic peptides. They have been synthesised in protected form in twelve steps using a unified strategy, with the introduction of the unsaturated sidechain in the final step of the synthesis from a common aldehyde intermediate. The synthesis features the ordered application of asymmetric aminohydroxylation and dihydroxylation reactions to efficiently introduce the stereochemistry of the targets with high selectivity.

Despite their simple structures, synthesis of 1(or 3)-acyl-sn-glycerols remains a challenge that cannot be ignored because of facile acyl migrations, which not only complicate the synthesis but also make direct GC or HPLC analysis unfeasible. Assessment of the optical purity of monoacylglycerols has, to date, relied almost exclusively on specific rotation data, which are small in value and thus insensitive to impurities. Now, a simple means to “magnify” the small specific rotations has been found, along with practical methods for the measurement of both 1,2-and 1,3-acyl migrations, which offer a convenient and straightforward alternative to Mori’s NMR analysis of Mosher esters. With the aid of these methods, a range of conditions for deacetonide removal were examined en route to the synthesis of two natural monoacylglycerols. Refined hydrolysis conditions, along with useful knowledge about the solubility and reactivity of substrates with an ultra long alkyl chain are also presented. Copyright

The synthesis of the phytotoxic lactone herbarumin III in 11 % overall yield by fermentation of broth and mycelium of the fungus Phoma herbarum is described. Keck’s asymmetric allylation and Sharpless epoxidation are applied to build the key fragment of the compound. A ring closing metathesis and esterification with 5-hexanoic acid are used to obtain the compound. The synthesis is initiated by the application of the catalytic asymmetric allyl protocol. Chain elongation of the aldehyde through Wittig olefination with triphenyl carbethoxymethyl phosphonium chloride supported on alumina under microwave irradiation provided the alpha, beta – unsaturated ester as the major product. The ring opening metathesis with Grubbs second-generation catalyst gave Herbarumin III as a clear oil. The complete procedure involved the synthesis of the compound from n-butanal in 11 % overall yield.

(Chemical Equation Presented) Eureka! The first conquest of the exceptionally potent cytotoxic agent amphidinolide H, which exhibits activity in the picomolar range against human epidermoid cancer cells, was long overdue. The successful route critically hinges upon the scrupulous optimization of the fragment-coupling events (see picture; RCM = ring-closing metathesis) and on the careful adjustment of the peripheral protecting-group pattern.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.COA of Formula: C46H65Cl2N2PRu, you can also check out more blogs about246047-72-3
