Compound: (11bR)-N,N-Bis[(1R)-1-phenylethyl]dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-amine, is researched, Molecular C36H30NO2P, CAS is 415918-91-1, about Palladium-Catalyzed Enantioselective Heteroarenyne Cycloisomerization Reaction. Author is Liang, Ren-Xiao; Song, Ling-Jie; Lu, Jin-Bo; Xu, Wei-Yan; Ding, Chao; Jia, Yi-Xia.

The extensively developed ene-type enantioselective cycloisomerization of classical 1,n-enynes provides an efficient approach to chiral cyclic 1,4-dienes. In contrast, the catalytic asym. heteroarenyne (heteroarene-alkyne) cycloisomerization involving the dearomative transformation of endocyclic aromatic C=C bonds remains unknown. Herein, we communicate a PdH-catalyzed enantioselective heteroarenyne cycloisomerization reaction of alkyne-tethered indole substrates (formal 1,5- and 1,6-enynes). Based on this strategy, a variety of structurally diverse chiral spiro and fused indoline derivatives bearing quaternary stereocenters and exocyclic C=C bonds are afforded in moderate to excellent yields and excellent enantioselectivities (up to 98% ee). The classical ene-type enantioselective 1,5-enyne cycloisomerization of N-vinylpropiolamides is also developed to afford chiral 2-pyrrolones in good to excellent ee values.

Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 415918-91-1, is researched, SMILESS is C[C@@H](N(P1OC2=CC=C3C=CC=CC3=C2C4=C5C=CC=CC5=CC=C4O1)[C@@H](C6=CC=CC=C6)C)C7=CC=CC=C7, Molecular C36H30NO2PJournal, Article, Research Support, Non-U.S. Gov’t, Angewandte Chemie, International Edition called Synthesis of allylic amines: Enantioselective allylation of aromatic amines after in situ generation of an activated cyclometalated iridium catalyst, Author is Shu, Chutian; Leitner, Andreas; Hartwig, John F., the main research direction is regioselective enantioselective allylation aromatic amine cyclometalated iridium phosphoramidite catalyst.Category: esters-buliding-blocks.

Highly regio- and enantioselective allylation of aromatic amines is observed when a cyclometalated Ir-phosphoramidite complex is generated in situ. The active catalyst can be formed from [{Ir(cod)Cl}2] and ligand L with a volatile alkylamine prior to addition of the reagents or upon use of a tertiary amine additive. E.g., a cyclometalated Ir-phosphoramidite complex catalyzed the allylation of PhNH2 by carbonate (E)-PhCH:CHCH2OC(O)OMe to give 80% (+)-PhCH(NHPh)CH:CH2.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: (11bR)-N,N-Bis[(1R)-1-phenylethyl]dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-amine, is researched, Molecular C36H30NO2P, CAS is 415918-91-1, about Enantioselective and diastereodivergent access to α-substituted α-amino acids via dual iridium copper catalysis.Name: (11bR)-N,N-Bis[(1R)-1-phenylethyl]dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-amine.

The work reported within this paper describes an example of the application of bimetallic catalysts system in allylic substitution reactions. The development of new nucleophiles and the control of enantio- and diastereoselectivity are the main research topics in this area. An improvement in the reactivity and diastereoselectivity has been realized for the dual Ir/Cu catalyzed allylic alkylation of inactive prochiral nucleophiles, under mild reaction conditions. Furthermore, the choice of the metallacyclic iridium complex and chiral Cu-Phox complex combination allows for access to all four stereoisomers from the same starting materials with excellent enantioselectivity and diastereoselectivity (up to >99% ee and >20:1 dr). Significantly, this method provides a stereodivergent access to 2-amino-3-methylpent-4-acid ester, an important fragment for the synthesis of Halipeptin A.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Non-stabilized nucleophiles in Cu-catalysed dynamic kinetic asymmetric allylic alkylation, published in 2015-01-15, which mentions a compound: 415918-91-1, mainly applied to copper catalyzed dynamic kinetic asym transformation racemic substrate; unstabilized nucleophile dynamic kinetic asym allylic alkylation mechanism; organometallic reagent preparation dynamic kinetic asym allylic alkylation; medicinal tuberculosis leprosy preparation; aminobenzoate biosynthesis inhibitor preparation, Reference of (11bR)-N,N-Bis[(1R)-1-phenylethyl]dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-amine.

The development of new reactions forming asym. carbon-carbon bonds has enabled chemists to synthesize a broad range of important carbon-containing mols., including pharmaceutical agents, fragrances and polymers. Most strategies to obtain enantiomerically enriched mols. rely on either generating new stereogenic centers from prochiral substrates or resolving racemic mixtures of enantiomers. An alternative strategy-dynamic kinetic asym. transformation-involves the transformation of a racemic starting material into a single enantiomer product, with greater than 50 per cent maximum yield. The use of stabilized nucleophiles (pKa < 25, where Ka is the acid dissociation constant) in palladium-catalyzed asym. allylic alkylation reactions has proved to be extremely versatile in these processes. Conversely, the use of non-stabilized nucleophiles in such reactions is difficult and remains a key challenge. Here we report a copper-catalyzed dynamic kinetic asym. transformation using racemic substrates and alkyl nucleophiles. These nucleophiles have a pKa of ≥50, more than 25 orders of magnitude more basic than the nucleophiles that are typically used in such transformations. Organometallic reagents are generated in situ from alkenes by hydrometallation and give highly enantioenriched products under mild reaction conditions. The method is used to synthesize natural products that possess activity against tuberculosis and leprosy, and an inhibitor of para-aminobenzoate biosynthesis. Mechanistic studies indicate that the reaction proceeds through a rapidly isomerizing intermediate. We anticipate that this approach will be a valuable complement to existing asym. catalytic methods.
