A specific derivative of heterocyclic compound having nitrogen atom and an organic electroluminescence device comprising the compound. An organic electroluminescence device comprising at least one of organic compound layers including a light emitting layer sandwiched between an anode and a cathode, wherein said at least one of the organic compound layers comprises the derivative of the heterocyclic compound having nitrogen atom as a sole component or as mixed component. The organic electroluminescence device achieves elevation of luminance and excellent efficiency of light emission, and also achieves long lifetime by an improvement of an electrode adhesion.
The present invention relate to a compound represented by the formula (I) or (II)
wherein
ring A is an optionally substituted ring (the ring should not be pyrrolidine, piperidine and piperazine),
ring B is an optionally substituted aromatic ring,
ring D is an optionally substituted ring,
R
1
and R
2
are each independently a hydrogen atom or a substituent,
R
3
is a hydrogen atom or a C
1-6
alkyl group, or R
3
is bonded to
ring A to form a non-aromatic ring,
ring Aa is an optionally substituted aromatic hydrocarbon,
Y is CH or N,
Ra
1
is an optionally substituted hydrocarbon group, and
Ra
2
and Ra
3
are each independently a hydrogen atom or a substituent,
or a salt thereof.
The present invention provides a compound having a DGAT inhibitory activity, which is useful for the treatment or amelioration of diseases or pathologies caused by high expression or high activation of DGAT.
