Cycloaddition of oxygen-functionalized nitrite oxides to the enamine from ethyl acetoacetate produces 4-ethoxycarbonyl-5-methylisoxazoles carrying a 3-tetrahydropyranyloxymethyl, 3-diethoxymethyl or 3-ethoxycarbonyl substituent; the 3-formylisoxazole is prepared from the former two and condensed in situ with phosphoranes to give 3-alkenylisoxazoles that are cleaved by hexacarbonylmolybdenum or hydrogenolysis to afford alpha-alkoxycarbonyl-beta-diketones.

A synthesis of a 1,3-dithiane corresponding to the C1-side chain of zaragozic acid D is described. An aldol reaction using an Evans oxazolidinone is the key step in controlling stereochemistry. Metallation of the derived dithiane monosulfoxide and coupling to an aldehyde effected construction of the C1-C7 bond. Subsequent steps are also reported, including acid-mediated ketalization resulting in formation of an advanced synthetic intermediate containing the bicyclic ketal core of the natural product.

Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 4062-60-6, molcular formula is C10H24N2, introducing its new discovery. COA of Formula: C10H24N2

The use of alkaline carbonates in a slighty hydrated solid-liquid aprotic organic media allowed the synthesis of alkenes from polyfunctionnal aldehydes or activated ketones with high yield in a Z preferential stereochemistry.The reaction mechanism proposed takes in account the specific use of water on the solvation of cationic species at the solid-liquid interface to explain the Z.E alkene ratio.

The utility of 4-substituted prolinols and their corresponding prolines in peptides, peptidomimetics, and natural products has motivated researchers to find new and efficient routes for their preparation. Herein, we report a general approach to the synthesis of Boc-protected 4-alkylprolinols and prolines via a divergent asymmetric hydrogenation strategy. Intermediate exocyclic olefins were prepared by Wittig-type reactions with ketone 6 and subjected to hydroxyl and sterically directed reductions. The Crabtree catalyst (Ir[COD] PyPCy3PF6) proved to be highly effective in diastereoselective hydrogenations to give trans- substituted pyrrolidines (9). Good facial selectivities were also observed in heterogeneous hydrogenations with Raney-nickel to obtain cis-substituted pyrrolidines (11). Employing this strategy, we describe the synthesis of novel prolinol and proline-based building blocks for incorporation into biologically relevant peptidomimetics.

A general method for alkali-metal-promoted reductive difunctionalization of alkenes has been developed by means of reduction-resistant alkoxy-substituted electrophiles. A series of 1,2-diboration and 1,2-dicarbofunctionalization products can be synthesized by employing trimethoxyborane and strained cyclic ethers such as oxirane and oxetane. In addition, unsymmetrical carbo- or thioborations have been accomplished via sequential treatment with trimethoxyborane and carbon or sulfur electrophiles.

Two natural diarylheptanoids, 2-benzyl-5-(2-phenylethyl)furan (1) and 2-methoxy-4-{[5-(2-phenylethyl)furan-2-yl]methyl}phenol (2), were synthesized starting from 2-furaldehyde. A Wittig reaction of 2-furaldehyde with benzyltriphenylphosphonium bromide followed by reduction of the alkene C=C bond with Mg gave 2-(2-phenylethyl)furan (5). Lithiation of 5 with BuLi at -78 followed by alkylation with benzyl bromide gave natural product 1. In another approach, Friedel-Crafts acylation of compound 5 with benzoyl chloride followed by deoxygenation of the C=O group afforded 1. The natural product 2 was also synthesized by acylation of 5 with 4-acetoxy-3-methoxybenzoyl chloride (16) followed by deoxygenation and deacetylation.

The Heck reaction between a carbohydrate 5,6-ene derivative 9 and an aromatic halide exclusively gave rise to the beta-carbohydrate-substituted trans-styrene derivative 8; while the corresponding Wittig reaction produced a cis/trans mixture in which the cis-isomer predominated. The application of the Heck reaction is described to synthesize the intermediate 5, commonly used in the synthesis of members of the crocacin family.

The E/Z ratios of the stilbenes 1 formed in the Wittig reaction of ortho-halo substituted benzyltriphenylphosphonium salts 2 and benzaldehydes 3 were determined. It was found that there is a co-operative effect of one ortho-halo group on each of the two reacting partners which increases Z-selectivity, but two such groups on the same reactant gives high E-selectivity. The effects are strong enough to be preparatively significant in certain cases and can be interpreted within the modern framework of the Wittig mechanism established by Vedejs and co-workers.
