✦ Synopsis

The recent articles by Pelletier 2B3 on the relative stereochemistry of the diterpene alkaloids of the veatchineatisine class4 prompt us to record some of our own results in this field. As will be shown below, our investigations establish the absolute configuration of the C/D ring juncture and by inference, the complete absolute configuration of this group of alkaloids.
