Abstract
Provided is a method of preparing asymmetric anthracene derivative, more particularly, a method for high-yield production of an anthracene derivative in which an alkyl group, a cycloalkyl group, a heterocycloalkyl group, an aryl group or a heteroaryl group is introduced at position 2 of anthracene, and an aryl group or a heteroaryl group is introduced at each of positions 9 and 10 of the anthracene.
Claims3
A method of preparing an anthracene derivative represented by Formula 5 below, the method comprising:
- (a) reacting a compound of Formula 1 below with a compound of Formula 2 below to obtain a compound of Formula 3 below;
- (b) cyclizing the compound of Formula 3 to obtain a compound of Formula 4 below;
- and
- (c) introducing an aryl group at position 10 of anthracene of the compound of Formula 4,
- wherein Z is MgX where X is halogen, Li, or Na;
- R2 is an alkyl group of C1˜C30, a cycloalkyl group of C5˜C30, a heterocycloalkyl group of C5˜C30, an aryl group of C5˜C30, or a heteroaryl group of C5˜C30;
- Ar2 is an aryl group of C5˜C30 or a heteroaryl group of C5˜C30;
- and
- wherein the alkyl group, cycloalkyl group, heterocycloalkyl group, aryl group and heteroaryl group are each independently unsubstituted or substituted by at least one selected from the group consisting of C1-C30 alkyl, C2-C30 alkenyl, C2-C30 alkynyl, C5-C30 aryl, C5-C30 heteroaryl, C5-C30 aryloxy, C1-C30 alkyloxy, C5-C30 arylamino, C5-C30 diarylamino, C5-C30 arylalkyl, C5-C30 cycloalkyl, C5-C30 heterocycloalkyl and a halogen atom.
