개요

This alkaloid is the major base found in Pachysandra terminalis Sieb. et Zucco Like the other alkaloids present in this plant, it contains the pregnane skeleton. It is dextrorotatory with [α]D + 24° (CHCI 3). It has two keto groups in the molecule, one being present in a four-membered ring. Reduction with NaBH4 furnishes Pachystermine B (q.v.). The structure has been confirmed by the partial synthesis of the alkaloid.
