## Abstract 1,2‐Didehydrocrotalanine (**2**) is the first synthetic macrocyclic pyrrolizidine alkaloid analogue to be studied by X‐ray crystallography. The crystal structure was solved by multisolution direct methods and refined by full‐matrix least‐squares to __R__ = 0.036 for 693 reflections. The
