The unusual migration of a nitro group from the β- to the α-position of a β-aryl-α-nitroethenyl moiety, following a nitrocyclopropane to isoxazoline N-oxide isomerization, has been studied from a mechanistic and synthetic points of view. As a result, two series of isomeric isoxazoline N-oxides could be obtained under controlled conditions. When...

The conjugated bis(sulfonyl)nitrobutadienes 1 undergo, with primary amines, competitive MeSO2 replacement [vinylic substitution at C(1)] versus aza-Michael addition to the nitroethenyl C(3)–C(4) double bond. The latter pathway eventually leads to the trisubstituted pyrroles 2 and conditions have been optimized in order to maximize the yield of...

2015 (v1)PublicationA straight access to functionalized carbazoles by tandem reaction between indole and nitrobutadienes
As a continuation of our research on the synthetic exploitation of the nitrobutadienic building-blocks obtained from the ring-opening of nitrothiophenes, we herein report about their reaction with the π-nucleophilic indole. Thanks to their double Michael-acceptor nature, 2,3-dinitro and 2-nitro-3-phenylsulfonyl substituted 1,3-butadienes...

The multifaceted behavior of nitrobutadienes deriving from the initial ring-opening of nitrothiophenes finds a further clear-cut example in their Michael-type acceptor reactivity towards indole. Thus, depending on the starting diene, either newly-functionalized indoles or carbazoles are produced, the latter as the result of an appealing double...

In prosecution of the synthetic exploitation of nitrobutadienes deriving from the initial ring-opening of nitrothiophenes, their multifaceted behavior finds a further clear-cut example in their Michael-type acceptor reactivity toward the anions of a-oxohydrazones. Thus, depending on the starting diene, new poly-functionalized pyrazoles are...
