چکیده

A mild, efficient and versatile method has been developed for the construction of a functionalized natural product, meridianin, and its post conversion to pyrimido-β-carboline by cationic π- cyclization. The strategy involves the introduction of an amino group at the C-5 of the pyrimidine ring and utilizing the nucleophilictiy of the C-2 in the indole ring to facilitate cationic π-cyclization.

Diastereoselective synthesis of bridged polycyclic alkaloids via tandem acylation/intramolecular Diels-Alder reaction.

A mild and efficient stereoselective synthesis of hexacyclic indole alkaloids with a tetrahydro-β-carboline motif has been developed by utilizing the Pictet-Spengler reaction and tandem N-acylation followed by intramolecular Diels-Alder cyclization. Initially, a diene unit was installed in the tetrahedron β-carboline skeleton through Pictet-Spengler cyclization of the corresponding aldehyde wit...

Construction of indole- and isoquinoline-fused nitrogen-containing heterocycles through copper-catalyzed multi-component reaction.

A copper-catalyzed synthesis of 2-(aminomethyl)indole through domino three-component coupling-cyclization has been developed. This reaction proceeds through Mannich-type coupling of 2-ethynylanilines, aldehydes, and secondary amines, followed by hydroamination. This indole formation was applicable to the synthesis of 4-methylene-2,3,4,9-tetrahyro-1H-pyrido[3,4-b]indoles and 5,6,7,8-tetrahydrobe...

A NEW STRATEGY FOR THE SYNTHESIS OF TRICYCLIC AND TETRACYCLIC SYSTEMS OF INDOLE ALKALOIDS

Reaction of tryptamine 1 with dimethyl -3-methoxyallylidenemalonate 2 afforded N?-[4,4-bis (methoxycarbonyl)-1,3-butadienyl] tryptamine 3 which in combination with acetylchloride and pyridine in dichloromethane gave N?, N?-[acetyl]-[(4,4-dinethoxycarbonyl) 1,3butadienyl] tryptamine 4. Treatment of 3 with sodium hydroxide afforded 2H[N-(3-indolyl) ethyl] 2-oxo-3-methoxycarbonyl-1-pyridine 5. Cy...

Asymmetric total synthesis of mycoleptodiscin A.

The first total synthesis of mycoleptodiscin A, a structurally unusual indolosesquiterpenoid possessing an ortho-benzoquinone motif, has been accomplished. A sulfone alkylation coupled two readily available fragments to give an aryl triene intermediate. The tetracyclic core of the molecule was assembled through a highly enantioselective iridium-catalyzed polyene cyclization. The benzylic homolo...

Ligand-controlled regiodivergent nickel-catalyzed annulation of pyridones.

The 1,6-annulated 2-pyridone motif is found in many biologically active compounds and its close relation to the indolizidine and quinolizidine alkaloid core makes it an attractive building block. A nickel-catalyzed C-H functionalization of 2-pyridones and subsequent cyclization affords 1,6-annulated 2-pyridones by selective intramolecular olefin hydroarylation. The switch between the exo- and e...
