Mass spectrometry of bisbenzylisoquinoline alkaloids. Part I. Alkaloids derived from coclaurine units joined tail-to-tail

Abstract

Mass spectrometric data are presented for some simple types of biscoclaurine alkaloids in which the two halves of the molecule are joined tail-to-tail by one, two, or three ether links. The cleavage patterns, supported in part by deuteriation experiments, are discussed.
