New applications of N-acyliminium precursors: Tetracarbonyliron-mediated stereoselective alkylations of 5-(R)-isopropoxy-3-pyrrolin-2-ones

Lewis acid catalyzed allylic substitutions with several nucleophiles at C-5 of the cis-tetracarbonyliron complexes of N-acetyl- and N-tosyl-5-(R) -isopropoxy-3-pyrrolin-2-ones occur highly regio- and stereoselectively. The results are interpreted as being indicative of the intermediacy of a ( pi-allyl)tetracarbonyliron cation, with possible preceding formation of an N-acyl- or an N-tosyliminium ion.

Anion polarity-induced dual oxidation states in a dual-layered purely organic paramagnetic charge-transfer salt, (TTF)(3)(PO-CON(CH3)C2H4SO3)(2), where PO=2,2,5,5-tetramethyl-3-pyrrolin-1-oxyl free radical

The purely organic paramagnetic charge-transfer salt (TTF)(3)(PO-CON(CH3)C2H4SO3)(2) was prepared. The anisotropic anion forms a head-to-head arrangement in the anionic layer, giving dual donor layers with different oxidation states. SQUID magnetometry indicates that spins are localized not only on the free radical (PO) but also on both TTF layers.

Synthesis and Transformation of Triterpenoids with a beta-Ketonitrile Fragment in Five-Membered Ring A

Triterpenoids with a beta-ketonitrile group in five-membered ring A were synthesized via intramolecular oxonitrile cyclization of C-3 methyl esters of 1-cyano-substituted 2,3-seco-triterpene acids. The intramolecular cyclization to form the triterpene ketonitriles and subsequent reduction of the oxo groups to give C-1 and C-3 substituents in the beta-orientation were confirmed to be stereoselective. Alkaline hydrolysis of the ketonitriles reduced the cyano groups to form the corresponding 3-oxo-2-nor-derivative while reduction and acylation of the beta-hydroxynitrile formed an alpha,beta-alkenenitrile fragment in the triterpenoid five-membered ring A.

Research Progress on [3+n](n >= 3) cycloaddition of 1,3-Diploes

Versatile heterocyclic skeletons extensively exist in structures of natural products, drug molecules and organic materials, and have been synthesized through various strategies reported in literatures. Among them, the 1,3-dipolar cycloaddition is the most impressive class to build the related heterocycles. In the past, organic chemists generally employed [3+2] cycloaddition of 1,3-dipoles to assemble five-membered rings. As modern chemistry developes, researchers further turn their attention to the [3+3], [3+4], [3+5] and [3+6] cycloadditions, to construct six-, seven-, eight- and bridge-heterocyclic compounds. At present, review articles with topics on 1,3-dipolar cycloaddition mainly focus on [3+2] cycloaddition. Herein, A topic on [3 + n] (n >= 3) cycloaddition of 1,3-dipoles, with comments on the developed methodologies is present and the out-look in this field is proposed.

Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons. Keep reading other articles of 636-41-9. Name: 2-Methyl-1H-pyrrole.

A scalable process for the synthesis of the bcl inhibitor obatoclax

Recently we created the novel indolylprodigiosin derivative 2 (obatoclax) and demonstrated its ability to antagonize multiple members of the B-cell lymphoma (Bcl) family of antiapoptotic proteins. The compound has shown potent anticancer activity in several animal tumor models. Obatoclax is now in Phase 1b and 2 clinical trials directed against multiple hematologic and solid tumor malignancies. To support its clinical development, a new scalable synthesis was required. Obatoclax has been prepared using a three-step synthesis, starting from commercially available 4-methoxy-3-pyrrolin-2-one. The reaction sequence involves a haloformylation reaction followed by a Suzuki cross-coupling reaction with an indole-2-boronic acid. The synthesis is completed by an acid-mediated condensation with 2,4-dimethyl-1H-pyrrole.
