Abstract
The reactions of the quaternary protoberberine alkaloids berberine and copt isine with liquid ammonia were investigated. 8-Amino-8H-berberine and 8-ami no-8H-coptisine were obtained as crystals directly from the reaction mixtur e. Their structures were determined by X-ray analysis and mass spectrometry .
