A convenient synthetic route to three-ring systems (11) and (12) related to those found in prodigiosin antibiotics is described: the X-ray crystal structure of (12) shows that the exocyclic double bond has a Z-configuration, which allows hydrogen bonding between the methoxy group and the pyrrole NH of ring C.
and formylation. Condensation of these aldehydes with activated pyrroles in the presence of phosphoryl chloride provides analogues of prodigiosin, which differ from the natural products in the nature of the heteroatoms. gas-phase reactions - heterocycles - pyrroles - prodigiosins
