All four stereoisomers of 2-alkyl-3,4-iminobutanic acid, a novel class of beta-amino acids bearing a chemically versatile aziridine ring, were synthesized starting with aspartic acid. The synthetic strategy involves the introduction of an alkyl group at the beta-position of fully protected optically active aspartic acid followed by the construction of an aziridine ring making use of the alpha-carboxylate and alpha-amino groups. The alpha-carboxylate was reduced to the corresponding alcohol, which was then subjected to cyclization to form an aziridine ring with the N-protected amino group. Removal of the protection groups yielded the target compounds.

The design and synthesis of related molecules that are more effective, more selective, and less toxic than aspirin are important objectives of biomedical research.Keep reading other articles of 87219-29-2. Electric Literature of 87219-29-2

Synthetic Route of 87219-29-2, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.87219-29-2, Name is (S)-Benzyl (5-oxotetrahydrofuran-3-yl)carbamate, molecular formula is C12H13NO4. In a Article，once mentioned of 87219-29-2

A general method has been developed for assigning the structures of nodularin, a potent hepatotoxin, tumor promoter, and protein phosphatase inhibitor, and minor components isolated from a cultured and a bloom sample of the cyanobacterium Nodularia spumigena. It consists of (1) FABMS analysis (determination of molecular weight and molecular formula), (2) 1H NMR spectroscopy on the parent compound and chiral GC analysis of an acid hydrolyzate (identification and stereochemistry of amino acid components), (3) ozonolysis followed by NaBH4 reduction (conversion to a linear peptide), and (4) FABMS/CID/MS analyses of the linear peptide and the parent compound (sequence analysis). The method has been employed in assigning structures to three new nodularins (2-4) and can be applied to other cyclic peptides containing alpha,beta-dehydroamino acid unit(s), especially the related microcystins, cyclic heptapeptide hepatotoxins. Two nodularins, [DMAdda3]nodularin (2) and [(6Z)Adda3]nodularin (3), were obtained from a bloom sample collected from Lake Ellesmere (New Zealand), and [D-Asp1]nodularin (4) was isolated from cultured cells (strain L-575). The LD50s of 2 and 4 were 150 and 75 mug/kg (ip, mice), respectively, but 3 did not show apparent toxicity at 2.0 mg/kg.

In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 87219-29-2, name is (S)-Benzyl (5-oxotetrahydrofuran-3-yl)carbamate, introducing its new discovery. Formula: C12H13NO4

1,4-Addition of benzylamine to 2(5H)-furanone followed by dialkylation of the 3-position with allylbromide gave (±)-4-benzyl-3,3-diallyl-2(3H)-furanone (8), which served as the intermediate for the synthesis of various N-substituted 4-amino-3,3-dipropyl-2(3H)-furanones (±)-9a-1. The compounds were evaluated for their capacity to potentiate or inhibit GABA-evoked currents in Xenopus laevis oocytes expressing recombinant alpha1beta2gamma2 GABAA receptors. The benzyl, ethyl, and allyl carbamates ((R)-9a (100 muM), (±)-9b (100 muM), (±)-9c (200 muM)) stimulated GABA currents by 279 ± 47%, 426 ± 8%. and 765 ± 61%, respectively, while the phenylcarboxamide (±)-9f (200 muM) stimulated currents by 420 ± 33%. Concentration-response studies showed that compound 9c was approximately twice as potent in stimulating GABA currents as alpha-EMTBL (2), the most potent 3,3-dialkylbutyrolactone known to date. On the other hand, the N-sulfonyl analogues were much less active or even inhibited GABA-evoked currents. In vitro radioligand displacement studies on rat brain membranes showed that these compounds did not bind to the benzodiazepine or GABA recognition sites of the GABAA receptor. However, these compounds generally weakly displaced [35S]-TBPS (approximately 50% displacement at 100 muM), though potencies did not correlate with GABA current potentiation. Results obtained with alpha1beta1 and mutant alpha1beta2N265S receptors, which compared to alpha1beta2 receptors are both much less sensitive to current stimulation produced by the anticonvulsant loreclezole, suggest that at least some of these aminobutyrolactones, (e.g., 9a, 9c), and interestingly also alpha-EMTBL, share stimulatory properties with loreclezole.
