The direct dehydrogenative C–H cleaving carbonylative lactamization of 2-arylanilines
promoted by visible light and potassium bases is reported. Solvent DMF acts as the sole …

Three S/Se-hetero [9] helicenes were synthesized by an assembly strategy of two building
blocks, phenanthrene and ternary fused S/Se-heteroaromatic ring, and characterized by …

Helicenes are an extremely interesting class of conjugated molecules without asymmetric
carbon atoms but with intrinsic chirality. These molecules can interact with double-stranded …

A new method for the stereoselective metal-, additive-and oxidant-free Friedel–Crafts-type
halo-carbocyclization of N-and O-tethered arene–olefin substrates is reported, involving …

We report a series of dibenzyl isophthalates (DBIs) as novel hosts for room-temperature
phosphorescence (RTP) host-guest systems, achieving RTP quantum yields (QY) of up to …

Racemic 9, 10-diketo [7] helicene was successfully separated into enantiomers using a
reversible and stereoselective reaction with 2, 2′-diamino-1, 1′-binaphthalene with …

Abstract Six [6] helicene based push-pull systems combining three diarylamines as donors
and two phosphine-oxides as acceptors were designed and synthesized in order to modify …

We report the concise synthesis and chir (optical) properties of an azaborathia [9] helicene
consisting of two thienoazaborole motifs. The key intermediate, a highly congested teraryl …

In recent years, the introduction of one or more heteroaromatic rings into a polyaromatic
backbone has attracted growing interest as it allows significant control over optical …

For the first time the possibility of regiospecific photocyclization of 3-amido-2-
arylbenzofurans was demonstrated. Distinctive feature of the studied photoreaction is …
