carbene complexes and dienophiles leading to the synthesis of phenanthridine ringsystem has been investigated. This reaction involves the generation of furo[3,4-c]isoquinolines as transient intermediates, which undergo [4+2] cycloaddition with a dienophile in an inter/intramolecular fashion. In fact, this is the first report of the work on furo[3,4-c]isoquinoline intermediates.

phenanthridine and acridine derivatives is described. This method includes the in situ generation of furo[3,4-c]isoquinoline and furo[3,4-b]quinoline intermediates by the coupling of heteroaromatic o-alkynyl carbonyl derivatives with Fischer carbene complexes and subsequent trapping of these intermediates by suitable dienophiles. azaisobenzofuran - heterocycles - Diels-Alder reaction - chromium - carbene complexes
