Nitrogen-embedded polycyclic compounds with strong antiaromaticity and stability were synthesized and isolated for the first time using pyrrole as a key unit. An expedited approach toward stable ...

Organic chemistry features a wide array of reactions for creating complex molecules, among which the Diels–Alder reaction stands out for its versatility and precision. This reaction enables the ...

Polycyclic aromatic compounds, characterised by fused aromatic rings, underpin advances in organic electronics, photonics and catalysis. Synthetic approaches broadly divide into bottom-up ...

The amount of environmental exposure to polycyclic aromatic hydrocarbons, or PAH for short, is strongly linked to a person's risk of developing rheumatoid arthritis, suggests research published in the ...

Polycyclic aromatic hydrocarbons are an important class of fused-ring natural compounds that are under fire for being toxic. Evidence suggests PAHs, which occur naturally in oil (including edible oils ...

Complex polycylic structures are found in nearly every biosynthetic class of natural products. In particular, an amazing range of rigid densely functionalized polycylic compounds are formed from ...

Eating your greens could be the secret to breathing easier, with a new study from Edith Cowan University (ECU) revealing that people who eat more vitamin K1-rich foods such as leafy green vegetables ...

Whenever an organic matter is burned, such as in a wildfire, a power plant, a car's exhaust, or in daily cooking, the combustion releases polycyclic aromatic hydrocarbons (PAHs) - a class of ...

Scientists have found that benzo(a)pyrene, traditionally measured to gauge risk of developing cancer from exposure to polycyclic aromatic hydrocarbons (PAHs), is a poor proxy for this type of cancer ...

The synthesis and isolation of a nitrogen-embedded polycyclic compound with strong antiaromaticity and stability was achieved for the first time by a research group at Ehime University. This result ...
