Description
- General description: (S)-(-)-α-Methylbenzyl isocyanate is a commonly used chiral derivatizing agent for the resolution of enantiomers.[1][2][3]
- Application: (S)-(-)-α-Methylbenzyl isocyanate may be used as a chiral auxiliary for the resolution of racemic (±)-6aR,11aR-maackiain to give the (-)-form, which is a key intermediate for synthesizing (-)-cabenegrin A-I.[4]
