Mass Spectrometric Studies of Methylenedioxybenzene Derivatives

The mass spectral fragmentations of methylenedioxybenzene derivatives are described. It has been reported that the methylenedioxy moiety of buphanasine, a member of Amaryllidaceae alkaloids, loses a molecule of formaldehyde by electron impact. However no detailed investigation of the mass spectral behaviors of methylenedioxy group has been carried out.In this paper the fragmentations of methylenedioxybenzene derivatives are discussed.
