Protostemonine-type alkaloids

Stemona alkaloids with a structure containing a pyrrolo[1,2-a]azepine skeleton (S1) , one 5-oxooxolane moiety (S2), and one a 5-(oxolan-2-yl)oxolan-2-one moiety (S3). The S2 moiety is linked to the C3 atom of the pyrrole ring in the S1 moiety. Additionally, the azepine ring of S1 is fused to one oxolane ring of the S3 moiety.
