substituent at the C6 position was achieved via intramolecular 6-endo-dig electrophilic cyclization under acidic conditions to construct the central aromatic C ring. Screening of the synthesized compounds using a high-content imaging system enabled us to discover novel dualstateemissive compounds 2 1,6}, 2 1,8}, and 2 4,3}, which are highly emissive with blue emission in their solid states as well

Provided is a benzo[b]naphtho[1,2-d]furan compound having a wide band gap which gives excellent color purity of blue. Further provided are a light-emitting element, a light-emitting device, and an electronic device each of which uses the benzo[b]naphtho[1,2-d]furan compound and is highly reliable. A benzo[b]naphtho[1,2-d]furan compound represented by a general formula (G1) is provided. In the general formula (G1), An represents an anthryl group represented by a general formula (An-1) or (An-2) below, α
1
and α
2
separately represent a substituted or unsubstituted phenylene group represented by any one of general formulae (α-1) to (α-3) below, and R
1
to R
9
separately represent either hydrogen or an alkyl group having 1 to 4 carbon atoms. Further, in the general formula (G1), n and m separately represent 0 or 1.
A novel heterocyclic compound that can be used as a host material in which a light-emitting substance is dispersed. A light-emitting element having a long lifetime. A heterocyclic compound in which a substituted or unsubstituted dibenzo[f,h]quinoxalinyl group is bonded to a substituted or unsubstituted arylene group having 6 to 25 carbon atoms which is bonded to any one of the 8-11 positions of a substituted or unsubstituted benzo[b]naphtho[1,2-d]furan skeleton.
An organic compound represented by General Formula (G1) that emits blue light with high color purity and has a long lifetime is provided as a novel substance. The organic compound is a fluorescent organic compound having a structure in which benzonaphthofuranylamine is bonded to the 1-position and the 6-position of a pyrene skeleton.
