Abstract
![]()
A transannular approach has been developed for the construction
of pyrrolo[1,2-b]isoquinolinones starting from benzo-fused
nine-membered enelactams. This process takes place in the presence
of a halogenating agent and under Brønsted acid catalysis and
proceeds via a transannular amidohalogenation, followed by elimination.
The reaction has been found to be wide in scope, enabling the formation
of a variety of tricyclic products in good overall yield, regardless
of the substitution pattern in the initial lactam substrate. The reaction
has also been applied to the total synthesis of a reported topoisomerase
I inhibitor and to the formal synthesis of rosettacin. Further extension
of this methodology allows the preparation of 10-iodopyrrolo[1,2-b]isoquinolinones by using an excess of halogenating agent
and these compounds can be further manipulated through standard Suzuki
coupling chemistry into a variety of 10-aryl-substituted pyrrolo[1,2-b]isoquinolinones.

Abstract
The total synthesis of dehydroantofine was achieved by employing a novel, regioselective, azahetero Diels-Alder reaction of easily accessible 3,5-dichloro-2H-1,4-oxazin-2-one with 14 a as a key step. Furthermore, it is demonstrated that dehydroantofine is a promising candidate as a new antimalarial agent in a biological assay with chloroquine-resistant Plasmodium falciparum.
