Notizen: Investigations into the parameters affecting the sensitivity of polarimetric detectors for the determination of enantiomeric excess by achiral HPLC are presented. The results obtained showed that the specific optical rotation of an analyte was highly sensitive to the methanol content of the mobile phase. The purpose of this short communication is to demonstrate that “off-line” optical rotation measurements are a necessary part of the method development process for successful use of polarimetric detectors.

Notizen: Certain abundant peaks in the electron impact mass spectra of a series of trans-4-benzoylamino-2H-1-benzopyran-3-ols involve the formation of a substituted N-alkylated benzonitrile ion by a mechanism involving migration of oxygen, in a postulated four-centre skeletal rearrangement, leading to the loss of a benzopyranone. The presence of a small range of differing substituents at three locations in this series was studied for their effects on this proposed mechanism.
