2-Formylergoline derivatives I and II were condensed with methyl isonitrilacetate in the presence of a base. Depending on the nature of this base, the main products of the reaction were either derivatives of pyrimido[1,6-a]ergoline, III and IV, or derivatives of 2-formylamino-3-oxo-3H-pyrrolo[1,2-a]ergoline, V and VI.
