Title:

OPTICALLY ACTIVE AMMONIUM SALT COMPOUND AND PRODUCTION INTERMEDIATE THEREOF

Document Type and Number:

Japanese Patent JP2012153691

Kind Code:

A

Abstract:

To provide an optically active quaternary ammonium salt compound useful as a chiral phase-transfer catalyst, and a production intermediate of the optically active quaternary ammonium salt compound.

The optically active quaternary ammonium salt compound is represented by formula (1). In the formula: R¹ is an alkyl or alkoxy; R² and R⁴ are hydrogen; R²¹ is hydrogen, alkyl or alkoxy; R³ is aryl or aralkyl; R⁵ and R⁶ are alkenyl and connects together to form an aromatic ring; * and ** show optical activity having shaft asymmetry; and X^- shows an anion.
