Jaewoong Kim and Chang Ho Oh* Department of Chemistry, Hanyang University, Wangsimni-ro 222, Seongdonggu, Seoul 04763, Korea Au-catalyzed cyclization of two propargylic carboxylate was developed by our lab. Au-activated di alkynyl phenyl compound b was transformed to naphthyl compound c. To extend this c for multi naphthyl compounds, naphthol compounds d (deprotected acetyl group) was applied for dendron, reacted with TCT(cyanuric chloride) and multi bromo alkyl compounds. In short, multi naphthyl compounds, having conjugated and non-conjugated central system, were synthesized. Finally, multi hydroxyl dendrimeric compounds were synthesized via MOM deprotection.
