A novel [3 + 3] cycloaddition between in situ formed azaoxyallyl cations and 2-alkenylindoles has been developed. This concise method allows the efficient construction of a series of tetrahydro-β-carbolinones in good yields under mild conditions. Gram-sca

A new domino synthetic approach for the synthesis of highly functionalized tetrahydrocarbazoles via DROC of various functionalized DA-cyclopropanes with 2-indolylnitroethylene and indole-substituted alkylidene malonate is described. The tetrahydrocarbazol

A novel uncatalyzed reaction between TpMo(CO)2(5- trifluoroacetoxy-η3-5,6-dihydropyranyl/dihydropyridinyl) complexes and electron-rich arenes/olefins is reported. The reaction proceeds under mild reaction conditions so that a variety of functional groups are tolerated. Combined with a stereospecific annulative demetalation, the new reaction provides a rapid access to polycyclic alkaloid structures. The sequential protocol was used to prepare analogues of the antimalarial agent isofebrifugine.

Indolylnitroethanes and their derivatives are key intermediates to many bioactive structures. Most approaches to access chiral indolylnitroethanes involve organocatalyzed or metal-catalyzed asymmetric Friedel-Crafts reaction of indoles with nitroalkenes.

A series of 2-and 3-indolylpyrroles were generated via 1,3-dipolar cycloadditions between (2-nitrovinyl)indoles and symmetrical and unsymmetrical 1,3-oxazolium-5-olates (muenchnones). The Japan Institute of Heterocyclic Chemistry.

N-Methyl-2-(2-methyl- (1), 2-methoxy- (2), and 2-ethoxycarbonyl- (3) -vinyl)indoles furnish the corresponding Diels-Alder adducts 5, 6 and 7 when treated with maleic anhydride.Under similar conditions N-methyl-2-(2-nitrovinyl)indole (4) undergoes dimerisation to give the dimer (8).Dimerisation to compound 17 is also observed during attempted separation of the mixture of cis- and trans-isomers of N-methyl-2-(2-methylvinyl)indole (1) on silica gel.The Diels-Alder adducts (5 and 7), on hydrolysis, followed by lead tetraacetate oxidation give the carbazoles, 11 and 14a + 14b respectively.
Synthesis of 2-amino-4-(2-benzofuryl)Δ1 pyrrolines and study of their antidysrhythmic properties
Maillard,Langlois,Vo Van,et al.
, p. 353 - 358 (2007/10/02)
The synthesis of 2-amino 4(2-benzofuryl)Δ1 pyrrolines, substituted in the aromatic ring and/or on the nitrogen atom of the amino group, is described. These derivatives are obtained from 3 (2-benzofuryl) acrylic esters, on which nitromethane is added. The reduction of 4-nitrobutyric esters lead to pyrrolidinones, and then to the entitled derivatives. Some analogs, the benzofuran ring of which is replaced by another heterocycle, were also prepared. Some of them exhibit interesting antidysrhythmic properties.
