Amaryllidaceae alkaloids

Isoquinoline alkaloids with a skeleton deriving from lycorine, norbelladine, homolycorine, hemanthamine, crinine, tazettine, montanine, plicamine, galanthindole, galanthamine, gracilline, among others. Amaryllidaceae Alkaloids represent a large group of biogenetically related isoquinoline alkaloids that are found exclusively in plants belonging to this family of Amaryllidaceae. This group of alkaloids is also derived from two tyrosine units which combine, with loss of one carbon atom, to give a benzylphenylethylamine precursor unit, e.g. Norbelladine, which by various oxidative cyclisation processes, prominent among which are phenol oxidative coupling reactions, can give rise to the nine major skeletal groups.
