Synthesis of the amaryllidaceae alkaloid, lycorine

Journal of the Chemical Society, Chemical Communications, 1975
A key intermediate for the total synthesis of lycorine has been prepared in racemic form; the optically pure form of this epoxylycorinane lactam, obtained from lycorine, has been reconverted into the alkaloid.

Amaryllidaceae Alkaloids and Colchicine

1968
About one hundred alkaloids are known from the family Amaryllidaceae. In their route of biosynthesis they bear several resemblances to the morphine alkaloids. In each type there are two six-membered rings derived from aromatic amino acids; and the additional ring closures are apparently produced by a mechanism of phenolate free radical coupling.

Alkaloid N-oxides of amaryllidaceae

Phytochemistry, 1988
Ungiminorine N-oxide was isolated from Pancratium maritimum, and homolycorine N-oxide and O-methyl lycorenine N-oxide from Lapiedra martinezii. These compounds represent the first examples of naturally occurring N-oxides from the Amaryllidaceae. © 1988.

Cytotoxic Lycorine Alkaloids of the Plant Family Amaryllidaceae

Bioorganic Chemistry
The plant family Amaryllidaceae is embellished with a diverse array of antiproliferative alkaloid principles. Chief amongst these are the lycorine alkaloids, which have attracted considerable attention as potential anticancer drugs. This account tracks developments in the field with these substances encompassing the years 2015-2019.
