Synthesis of 1,8-di(1-adamantyl)naphthalenes as single enantiomers stable at ambient temperatures

Aikawa, Haruo,Takahira, Yusuke,Yamaguchi, Masahiko

, p. 1479 - 1481 (2011/03/22)

Single enantiomers of 1,8-di(1-adamantyl)naphthalenes were synthesized by the [4+2]cycloaddition reaction of 6-adamantylbenzyne and 2-adamantylfuran. The enantiomers were resolved by conversion into diastereomeric ketopinic acid esters. The absolute confi
