Modular De novo Synthesis of Unsymmetrical BODIPY Dyes Possessing Four Different Aryl Substituents

A modular synthesis of unsymmetrical BODIPY dyes based on a [6π] electrocyclization to construct both pyrrole rings is presented. The products carry four aryl moieties in positions 1, 3, 5, and 7, which can be freely selected, as well as optional substitution in positions 2 and 8. The method employs acetophenones, benzaldehydes as well as glycine nitrile or glycine ethyl ester as the key building blocks.

Synthesis of polysubstituted pyrroles via [3 + 2]-annulation of aziridines and -nitroalkenes under aerobic conditions

Polysubstituted pyrroles were regioselectively synthesized in moderate to good yields via the copper acetate-catalyzed [3 + 2] annulation reaction of readily accessible aziridines and nitroalkenes. This reaction was proposed to proceed through a key azomethine ylide intermediate generated by selective C-C bond cleavage of the aziridine followed by annulation with nitroalkenes under aerobic conditions.

Three-component synthesis of polysubstituted pyrroles from α-diazoketones, nitroalkenes, and amines

Polysubstituted pyrroles are regiospecifically synthesized via the copper-catalyzed three-component reaction of α-diazoketones, nitroalkenes, and amines under aerobic conditions. The cascade process involves an N-H insertion of carbene, a copper-catalyzed

CYCLIZATION OF 2,4-DICHLORO-1,5-PENTANEDIONES WITH NUCLEOPHILIC REAGENTS

The mechanism of reaction of 2,4-dichloro-1,5-pentanediones with ammonia has been studied.Intramolecular cyclization of the intermediate resulting from nucleophilic attack at the carbonyl group can occur in two ways, depending on the reaction conditions,

Eine bequeme Synthese von 2-Aroyl-5-arylpyrrolen

2-Aroyl-5-arylpyrroles are prepared in 20-60percent yields by cyclocondensation of 1,5-diaryl-2-methylsulfinyl-1,5-pentanediones with ammonium acetate in acetic acid.
