A new and a convenient route to enaminones and pyrazoles

A new method has been developed for the regioselective preparation of enaminones and pyrazoles from 1,3-diketonatoboron difluorides. The reactions proceed smoothly under mild reaction conditions, producing enaminones and pyrazoles in high yields.

BX 3-Mediated Intermolecular Formation of Functionalized 3-Halo-1 H-indenes via Cascade Halo-Nazarov-Type Cyclization

A BX 3-promoted, intermolecular regioselective synthesis of 3-halo-functionalized 1 H-indenes from 4-oxo-4 H-chromene-3-carb?-aldehydes and alkynes has been developed. BX 3 displays a dual role of Lewis acid catalyst and halide source for haloallyl cation formation for the intended halo-Nazarov-type cyclization. The overall transformation represents an efficient cascade annulation that employs readily available starting materials, inexpensive reagents and a convenient and mild reaction procedure to generate halo-functionalized indenes (45 examples). The reaction was also extended to 8-formylcoumarins to deliver coumarin-based 3-halo-1 H-indenes in 79-95percent yield (6 examples). The reaction involves conversion of the aldehyde into an sp 3 carbon with two new C-C bonds and additionally a C-X bond is formed (X = halide).

Dicyanoboron diketonate dyes: Synthesis, photophysical properties and bioimaging

A new class of dicyanoboron diketonates (B(CN)2) was synthesized and the photophysical properties were investigated. The B(CN)2 complexes exhibited high molar absorption coefficients, large Stokes shifts, high photostability and low cytotoxicity. Especially, the emission of the B(CN)2 extended into the deep red region. The extensive π conjugation and the presence of intramolecular charge transfer (ICT) transitions are responsible for their red-shifted emission. Their fluorescence are very sensitive to the polarity of the solvents. They are highly emissive in low polarity solvents, but weakly fluorescent in polar solvents. Cell imaging experiments demonstrated its potential application as a probe in bioorganisms due to its excellent imaging contrast. This strategy represents a facile approach to modulate the photophysical properties of dyes.
