摘要：

This invention relates to processes for the preparation of antiparasitic isoxazoline compounds enriched in an enantiomer using quinine- based chiral phase transfer catalysts. The invention also relates to novel quinine-based phase transfer catalysts and to a crystalline toluene solvate form of (S)-afoxolaner.
