An efficient asymmetric synthesis of furofuran lignans: (+)-Sesamin and (-)-sesamin

An efficient synthesis of (+)-sesamin 1a and (-)-sesamin 1b is described. The key reactions include highly stereoselective aldol condensation of piperonal 7 with the dianion of chiral oxazolidinone 8, followed by intramolecular ring cyclization of aldol product 11 in high yield.

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.Recommanded Product: 102029-44-7, you can also check out more blogs about102029-44-7

Total synthesis of (+)-A83543A [(+)-lepicidin A]

The first synthesis of the macrolide insecticide A83543A (lepicidin A) has been completed using a Diels-Alder strategy to construct the carbocyclic framework. Diene synthesis through Pd-catalyzed Stille coupling of a macrocyclic vinylstannane and suitably functionalized vinyl iodide was followed by a diastereoselective Lewis acid-mediated intramolecular Diels-Alder reaction to construct the trans hydrindene subunit. Refunctionalization and intramolecular aldol condensation afforded the differentially protected (+)-lepicidin A aglycon. Successive glycosidations with 2,3,4-tri-O-methyl-D-rhamnose and N-protected L-forosamine followed by deprotection and methylation completed the synthesis of the enantiomer of the natural product.

Structure-activity relationship studies of S1P agonists with a dihydronaphthalene scaffold

Structure-activity relationship (SAR) of sphingosine-1-phosphate receptor agonists with a dihydronaphthalene scaffold was investigated. Compound 1 was modified to improve S1P1 agonistic activity and in vivo peripheral lymphocyte lowering (PLL) activity without impairing selectivity over S1P 3 agonistic activity. A detailed SAR study of the terminal lipophilic part revealed that the introduction of substituents on the propylene linker and the terminal benzene ring influences in vitro and PLL activities. Compound 6n bearing a (S)-methyl group at the 2-position on the propylene linker and chlorine at the para-position on the terminal benzene ring showed potent hS1P1 agonistic activity with excellent selectivity over hS1P 3 and in vivo PLL activity in mice.

Anticonvulsants in epileptic fowl

The high seizure susceptibility in epileptic fowl is an autosomal recessive trait characterized in homozygotes by seizures that occur spontaneously and in response to photic stimulation or hyperthermia. Both of the latter stimuli can be used to evoke seizures in drug studies. Epileptic fowl have abnormal inter-ictal EEG activity. When exposed to photic stimulation spiking is apparent on the EEG at seizure onset. Phenobarbital, primidone, phenytoin, and valproic acid reduce seizure susceptibility at plasma concentrations approximating those used to control generalized and focal cortical tonic-clonic seizures in humans. Carbamazepine and the benzodiazepines also reduce seizure susceptibility. These data include that epileptic fowl provide a useful model for generalized and focal cortical tonic-clonic epilepsies. Ethosuximide was inactive in epileptic fowl. However, trimethadione had anticonvulsant activity indicating that this model is only relatively specific for the above seizure types. When seizures were evoked by hyperthermia phenobarbital but not phenytoin or valproate reduced seizure susceptibility. GABA (gamma-aminobutyric acid), AOAA (amino-oxyacetic acid) and THPO (4,5,6,7-tetrahydroisoxazolo[4,5-c] pyridin-3-ole, a glial specific inhibitor of GABA uptake) all have anticonvulsant activity against seizures evoked by photic stimulation in young chicks. These data indicate that this model may be particularly useful for studies of the anticonvulsant activity of compounds designed to enhance GABAergic transmission.

Oligopeptides and copeptides of homochiral sequence, via beta-sheets, from mixtures of racemic alpha-amino acids, in a one-pot reaction in water; relevance to biochirogenesis

As part of our studies on the biochirogenesis of peptides of homochiral sequence during early evolution, the formation of oligopeptides composed of 14-24 residues of the same handedness in the polymerization of DL-leucine (Leu), DL-phenylalanine (Phe), and DL-valine (Val) in aqueous solutions, by activation with N,N?-carbonyldiimidazole and then initiation with a primary amine, in a one-pot reaction, was demonstrated by MALDI-TOF MS using deuterium enantio-labeled alpha-amino acids. The formation of long isotactic peptides is rationalized by the following steps occurring in tandem: (i) creation of a library of short diasteroisomeric oligopeptides containing isotactic peptides in excess in comparison to a binomial kinetics, as a result of an asymmetric induction exerted by the N-terminal residue of a given handedness; (ii) precipitation of the less soluble racemic isotactic penta- and hexapeptides in the form of beta-sheets that are delineated by homochiral rims; (iii) regio-enantiospecific chain elongation occurring heterogeneously at the beta-sheets/solution interface. Polymerization of L-Leu with L-isoleucine (Ile) or L-Phe with L-1N-Me-histidine yielded mixtures of copeptides containing both residues. In contrast, in the polymerization of the corresponding mixtures of L- + D-alpha-amino acids, the long oligopeptides were composed mainly from oligo-L-Leu and oligo-D-Ile in the first system and oligo-D-Phe in the second. Furthermore, in the polymerization of mixtures of hydrophobic racemic alpha-amino acids DL-Leu, DL-Val, and DL-Phe and with added racemic DL-alanine and DL-tyrosine, copeptides of homochiral sequences are most dominantly represented. Possible routes for a spontaneous “mirror-symmetry breaking” process of the racemic mixtures of homochiral peptides are presented.

Chiral building blocks: Enantioselective syntheses of benzyloxymethyl phenyl propionic acids

The synthesis of (2S)-2-benzyloxymethyl-3-(2-fluoro-4-methoxyphenyl)- propionic acid, (2S)-2-benzyloxymethyl-3-(2-fluoro-4-methylphenyl)propionic acid and (2S)-2-benzyl-oxymethyl-3-(2,4-dimethylphenyl)propionic acid has been achieved by TiCl4 mediated alkylation of the corresponding (4R)-4-benzyl-3-[3-(2-fluoro-4-methoxyphenyl-, 2-fluoro-4-methylphenyl-, 2,4-dimethylphenyl-)propionyl]-2-oxazolidinones, followed by hydrolysis of the chiral auxiliary. The stereochemistry of the alkylation reaction was confirmed by an X-ray crystal structure of (4R)-4-benzyl-3-[(2S)-2-benzyloxymethyl-3-(2- fluoro-4-methylphenyl)propionyl]-2-oxazolidinone.

Preparation and opioid activity of analogues of the analgesic dipeptide 2,6-dimethyl-L-tyrosyl-N-(3-phenylpropyl)-D-alaninamide

A number of analogues of the recently disclosed analgesic dipeptide 2,6- dimethyl-L-tyrosyl-D-alanine-phenylpropylamide (SC-39566, 2) were prepared. These analogues contained oxymethylene, aminomethylene, ketomethylene, bismethylene, and trans double bond (including vinyl fluoride) isosteric replacements for the amide bond between the D-alanine and phenylpropylamine units in 2. These compounds were tested in opioid binding assays and in the mouse writhing assay for analgesic activity. Though not as potent as 2, the oxymethylene, and trans double bond isosteres showed analgesic activity. The aminomethylene analogues also showed binding activity in subnanomolar concentrations at the mu receptor. The amide bond between 2,6-dimethyl-L- tyrosine and D-alanine units seems to be critical for opioid activity.
