22 - 147Regioselective Synthesis of Pyrroloquinolines – Approaches to Mar-tinelline. — Diels–Alder reaction of imines with cyclic enamides catalyzedby indium trichloride affords cis-fused pyrroloquinolines which form the corestructure of martinelline. The mixtures of endo and exo isomers are readilyseparated by chromatography. — (HADDEN, MARK; STEVENSON, PAULJ.; Tetrahedron Lett. 40 (1999) 6, 1215-1218; Sch.
