Total synthesis and stereochemical assignment of (±)-epiderstatin
An efficient total synthesis of the glutarimide-based natural product, (±)-epiderstatin 1, in 38% overall yield from acid chloride 4, is described. This study has also allowed for assignment of the C3/C5-relative stereochemistry as trans.

Structure and Stereochemistry of Lactams and Cyclic Imides. V. Mass Spectrometry of Substituted Glutarimides
Fragmentation pathways of cyclic imides based on high resolution MS measurements of six mono-, di- and trimethyl glutarimides are proposed.They can be treated as general ones.Most of integral ions have been found to consist of two different ones, which was not observed before.Relationship between the structures and abundances of several integral ions derived from substituted glutarimides has been observed.
