Singlet oxygen oxidation of pyrroles: Synthesis and chemical transformations of novel 4,4-bis(trifluoromethyl)imidazoline analogs

Article abstract of DOI:10.1016/0040-4020(96)00578-9

A novel singlet oxygen ring cleavage of pyrrole 5a and subsequent acid-catalyzed facile dehydrocyclization afforded a new series of 4,4-bis(trifluoromethyl)imidazolines with a p-fluorophenacyl side chain at the 5-position, which have shown potent acyl CoA: cholesterol acyltransferase (ACAT) and cholesterol biosynthesis inhibitory activities.
