So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Wang, Lei; Li, Sun; Bluemel, Marcus; Puttreddy, Rakesh; Peuronen, Anssi; Rissanen, Kari; Enders, Dieter researched the compound: (5aS,10bR)-2-(2,6-Diethylphenyl)-4,5a,6,10b-tetrahydro-2H-indeno[2,1-b][1,2,4]triazolo[4,3-d][1,4]oxazin-11-ium tetrafluoroborate( cas:1787246-78-9 ).Recommanded Product: 1787246-78-9.They published the article 《Switchable Access to Different Spirocyclopentane Oxindoles by N-Heterocyclic Carbene Catalyzed Reactions of Isatin-Derived Enals and N-Sulfonyl Ketimines》 about this compound( cas:1787246-78-9 ) in Angewandte Chemie, International Edition. Keywords: spirocyclopentane oxindole preparation heterocycle carbene catalyst enal sulfonyl ketimine; N-heterocyclic carbenes; asymmetric synthesis; heterocylces; organocatalysis; spiro-compounds. We’ll tell you more about this compound (cas:1787246-78-9).

A novel NHC-catalyzed annulation protocol for the asym. synthesis of biol. important β-lactam fused spirocyclopentane oxindoles with four contiguous stereocenters, including two quaternary carbon centers, was developed. Alternatively, spirocyclopentane oxindoles containing an enaminone moiety can be achieved using the same starting materials, isatin-derived enals, and N-sulfonyl ketimines, in the presence of a slightly different NHC catalytic system. This switchable annulation strategy enables the selective assembly of both heterocyclic scaffolds with good yields and excellent enantioselectivities for a broad range of substrates.

This literature about this compound(1787246-78-9)Recommanded Product: 1787246-78-9has given us a lot of inspiration, and I hope that the research on this compound((5aS,10bR)-2-(2,6-Diethylphenyl)-4,5a,6,10b-tetrahydro-2H-indeno[2,1-b][1,2,4]triazolo[4,3-d][1,4]oxazin-11-ium tetrafluoroborate) can be further advanced. Maybe we can get more compounds in a similar way.

A highly enantioselective intramol. annulation reaction of 1,3-diols catalyzed by a triazolium N-heterocyclic carbene (NHC) precatalyst is disclosed, affording the corresponding medium-sized lactones in moderate to good yields with high enantioselectivities. It is worth noting that this compatible catalytic system was successfully applied to assemble a broad range of chiral medium-sized lactones, including ones with eight-, nine-, ten-, eleven-, and twelve-membered rings.

The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions.

Keywords: carbene catalysis mellolide protoilludane marasmane sesquiterpenoid synthesis; N-heterocyclic carbenes; armillaridin; marasmane; protoilludane; total synthesis. Let’s learn more about this compound (cas:1787246-78-9).

The Armillaria and Lactarius genera of fungi produce the antimicrobial and cytotoxic mellolide, protoilludane, and marasmane sesquiterpenoids. We report a unified synthetic strategy to access the protoilludane, mellolide, and marasmane families of natural products. The key features of these syntheses are (1) the organocatalytic, enantioselective construction of key chiral intermediates from a simple achiral precursor, (2) the utility of a key 1,2-cyclobutanediol intermediate to serve as a precursor to each natural product class, and (3) a direct chem. conversion of a protoilludane to a marasmane (I → II) through serendipitous ring contraction, which provides exptl. support for their proposed biosynthetic relationships.
