Abstract

The title compound, 2-hydroxyphenyl 5-(pyrrol-2-yl)-3H-pyrrolizin-6-yl ketone, C(18)H(14)N(2)O(2), was isolated from the base-catalyzed 1:2 condensation of 2-hydroxyacetophenone with pyrrole-2-carbaldehyde. The pyrrole N-H and hydroxybenzoyl O-H groups are hydrogen bonded to the benzoyl O atom. The allylic C=C double bond of the 3H-pyrrolizine system is located between ring positions 1 and 2, the C atom at position 3 (adjacent to the N atom) being single bonded.
