Palladium-catalyzed direct arylation of maleimides: A simple route to bisaryl-substituted maleimides

Palladium-catalyzed direct arylation of maleimides via Heck as well as organoboron-mediated Heck-type reactions are developed. These methods offer an approach to a wide variety of biologically interesting 3,4-diarylmaleimide scaffolds from readily accessible starting materials. These approaches led to the feasible one-pot construction of bisaryl-substituted maleimides which have historically been problematic.

Biomimetic total synthesis of polycitrin A

The synthesis of the marine alkaloid polycitrin A (1a) is described. The synthesis is based on the formation of 3,4-bisarylpyrrole-2,5-dicarboxylic acids from 3-arylpyruvic acids by oxidative coupling and consecutive pyrrole ring formation. The pyrrole di

Structures and photophysical properties of 3,4-diaryl-1H-pyrrol-2,5-diimines and 2,3-diarylmaleimides

Structural features of 3,4-diaryl-1H-pyrrol-2,5-diimines and their derivatives have been studied by molecular spectroscopy techniques, single-crystal X-ray diffraction, and DFT calculations. According to the theoretical calculations, the diimino tautomeri

Diarylmaleic anhydrides: unusual organic luminescence, multi-stimuli response and photochromism

Diarylmaleic anhydride derivatives containing benzene (BPMA), thiophene (BTMA) and indole (BIMA) exhibit diverse and distinct fluorescence: aggregation-caused quenching (ACQ) of red emission of BIMA, blue aggregation-induced emission (AIE) of BPMA, and green dual-state emission (DSE) of BTMA in both solution and the solid state. Theoretical calculation and crystal structure analysis indicate that intramolecular and intermolecular interactions are responsible for their different emission behavior. A series of DSE-active molecules with full-color emission could be developed for the first time, through modification of the structures of BPMA and BIMA. Interestingly, BTMA and BPMA display multi-stimuli-responsive luminescence with a high-contrast (Δλem > 100 nm) and an unusual photochromic phenomenon in dichloromethane, which were utilized to construct rewritable data storage and mimic molecular logic operation (4-to-2 encoder and 1?:?2 demultiplexer), respectively.
